improve caching of images

First, we used two caches. Turns out that lru_cache wasn't needed, the
dict works perfectly fine on it's own.

Second, we now also cache local images, so that we don't have to read
them off the filesystem and convert them to base64 on every keystroke

Maybe there should be a maximum size on that cache dict, but I doubt
anyone would actually run into any trouble this cache taking too much
ram.

 # MarkdownLivePreview
 
-This is a sublime text **3** plugin that allows you to preview your markdown instantly *in* it!
+A simple plugin to preview your markdown as you type right in Sublime Text.
+No dependencies!
 
-### Dependencies
+## How to install
 
-**None! There is no dependency!** It uses [markdown2](https://github.com/trentm/python-markdown2) but it's a one file plugin, so it's included in the package.
+It's available on package control!
 
-## Installation
+## How to contribute
 
-MarkdownLivePreview is available on the default channel of
-[PackageControl](http://packagecontrol.io), which means you just have to
+If you know what feature you want to implement, or what bug you wanna fix, then
+go ahead and hack! But if you wanna contribute just to say thanks, and don't
+really know what you could be working on, then there are a bunch of `FIXME`s
+in `MarkdownLivePreview.py` and `markdown2html.py` (GitHub only shows the top
+2 results if you try to search using their interface :slightly_frowning_face:).
 
-1. Open the command palette (`ctrl+shift+p`)
-2. Search for: `Package Control: Install Package`
-3. Search for: `MarkdownLivePreview`
-4. hit <kbd>enter</kbd>
+### Hack it!
 
-to have MarkdownLivePreview working on your computer. Cool right? You can
-[thank package control](https://packagecontrol.io/say_thanks) for this. :wink:
+1. Fork this repo
+2. Make your own branch (the name of the branch should be the feature you are
+   implementing eg. `improve-tables`, `fix-crash-on-multiple-preview`
+3. All your code should be formated by black.
+4. Send a PR!
 
-### Usage
-
-You can choose to enable MarkdownLivePreview by pressing <kbd>alt+m</kbd> or selecting in the
-command palette `MarkdownLivePreview: Edit Current File`. Note that you need to be editing (simply
-having the focus on) a markdown file. Because [Markdown Extended][markdown-extended] did a good job,
-it's compatible with this plugin.
-
-So, once you've run it, it will open a new window, with only your markdown file, with the preview.
-Once you're done, close whichever file and it'll close the entire window.
-
-*Notice that it will close the entire window if you close __whichever__ file. It means that if you*
-*open a random file in this window, and then close it, it'll close the entire window still*
-
-For further infos, please [read the docs](https://math2001.github.io/MarkdownLivePreview/)!
-
-### Demo
-
-![demo](demo.gif)
-
-### Somethings wrong!!
-
-If you find that something's wrong with this package, you can let me know by raising an issue on the
-[GitHub issue tracker][github-issue-tracker]
-
-### How to open the [README][]
-
-Some of the package add a command in the menus, others in the command palette, or other nowhere.
-None of those options are really good, especially the last one on ST3 because the packages are
-compressed. But, fortunately, there is plugin that exists and **will solve this problem** for us

-# Welcome to MarkdownLivePreview's documentation!
-
-<img src="imgs/MarkdownLivePreview.svg" alt="MarkdownLivePreview's logo"
-     style="width: 400px; margin: auto; display: block;">
-
-MarkdownLivePreview is a [Sublime Text 3][st] plugin to preview your markdown as you type,
-*right in Sublime Text itself*, without *any* dependency!
-
-It's very easy to use, but there's a few things that you might want to be aware of... So, let's
-get started
-
-## Installation
-
-### Using Package Control
-
-You can really easily install MarkdownLivePreview by using [Package Control][pck-con].
-
-If it's not already, you need to [install it][install-pck-con] first.
-
-!!! note
-    If you're using the latest build of Sublime Text 3, you can just do
-    *Tools → Install Package Control…*
-
-- Open up the command palette (<kbd>ctrl+shift+p</kbd>)
-- Search up `Package Control: Install Package` (might take a few seconds)
-- In the panel that just showed up, search for `MarkdownLivePreview`
-
-Done! You have now access to every single features of MarkdownLivePreview! :wink:
-
-### Using `git`
-
-```sh
-$ cd "%APPDATA%\Sublime Text 3\Packages"             # on Windows
-$ cd ~/Library/Application\ Support/Sublime\ Text\ 3 # on Mac
-$ cd ~/.config/sublime-text-3                        # on Linux
-
-$ git clone "https://github.com/math2001/MarkdownLivePreview"
-```
-
-> So, which one do I pick?!
-
-I depends of what you want to do. If you want to just use MarkdownLivePreview, pick the first
-solution, you'll get every update automatically. But if you want to contribute, then choose the
-second solution.
-
-## Usage
-
-### Previewing
-
-As told in the introduction, MarkdownLivePreview is very easy to use:
-
-- open a markdown file
-- press <kbd>alt+m</kbd>
-- or select in the command palette `MarkdownLivePreview: Edit Current File`
-
-!!! note
-    The preview of unsaved markdown files is currently not supported. It should be fixed soon.
-
-!!! tip
-    [Markdown Extended][] is supported too!
-
-That's it. That's all you need to do to preview your markdown!
-
-### Settings
-
-To edit MarkdownLivePreview's settings, you just need to search in the command palette
-`Preferences: MarkdownLivePreview Settings`, or from the menus:
-*Preferences → Package Settings → MarkdownLivePreview → Settings*
-
-Do not edit the left file (by default, you cannot), but the right one. This right file will
-override the default one (on the left), and will be saved in your `User` folder, which makes it easy
-to back up.
-
-- `markdown_live_preview_on_open`: if set to `true`, as soon as you open a markdown file, the
-preview window will popup (thanks to[@ooing][] for its [suggestion][@ooing suggestion]). Default to
-`false`
-- `load_from_internet_when_starts`: every images that starts with any of the string specified in
-this list will be loaded from internet. Default to `["http://", "https://"]`
-- `header_action`: If you're writing a blog with some markdown and a static website generator, you
-probably have a YAML header. By default, this header will be displayed in a `pre` block. If you want
-to hide it, then just change the value to `remove`. Thanks to [@tanhanjay][] for
-[letting me know][front-matter-issue]!
-- `keep_open_when_opening_preview`: Each time the preview window is opened, the original markdown
-view is closed. If you want to keep it opened, just set this setting to `true`
-
-### Custom CSS
-
-If you want to, you can add custom `CSS` to the MarkdownLivePreview's default stylesheet.
-
-Just search for `MarkdownLivePreview: Edit Custom CSS File` in the command palette
-(<kbd>ctrl+shift+p</kbd>). It will open a file in which you can add some CSS that will be *added* to
-the normal CSS.
-
-!!! bug
-    Comments in the CSS is interpreted weirdly by Sublime Text's phantoms. After a few tests, I
-    think that everything that is bellow a comment is ignored.
-
-    If you want to be sure that your CSS works, don't put any comments in it
-
-#### Share your tweaks!
-
-If you think that other users would enjoy your added CSS, then raise an issue, or PR the
-[GitHub repo][] to share your tweaks!
-
-### Clearing the cache
-
-MarkdownLivePreview has a cache system to store images you load from internet. You can clear this
-cache by searching up in the command palette `MarkdownLivePreview: Clear the cache`.
-
-!!! tip
-    The cache is one simple file called `MarkdownLivePreviewCache`, which is located in your temp
-    folder. To know where it is, you can open the Sublime Text console (<kbd>ctrl+`</kbd> or
-    *View → Show Console*), and paste this in:
-
-    ```python
-    import tempfile; print(tempfile.gettempdir())
-    ```
-
-### Custom settings for the preview
-
-Sublime Text makes it easy to set custom settings for a specific *type* of view. For example,
-`markdown`, `python`, etc. MarkdownLivePreview takes advantage of that: the preview view (the view
-on the right) is a specific syntax (called — sorry for the originality —
-`MarkdownLivePreviewSyntax`). So, to change this, you can focus the right view, open up the command
-palette (<kbd>ctrl+shift+p</kbd>), and search up `Preferences: Settings — Syntax Specific`. In here,
-you can specify any settings that is going to be applied only to this view.
-
-### The hacky part
-
-In fact, MarkdownLivePreview parses those settings, and looks for specific ones:
-
-- `show_tabs`
-- `show_minimap`
-- `show_status_bar`
-- `show_sidebar`
-- `show_menus`
-
-Those settings aren't supported by default because they affect the entire *window* instead of just
-the view. But MarkdownLivePreview will look for them in your *preview*'s settings, and hide/show the
-tabs, the minimap, etc...
-
-As you probably guessed those settings takes a bool for value (`true` or `false`).
-
-### Recommendation
-
-Here's what I'd recommend for your MarkdownLivePreviewSyntax's settings (and what I use):
-
-```json
-{
-    "show_menus": false,
-    "show_tabs": false,
-    "show_minimap": false,
-    "gutter": false,
-    "rulers": [],
-    "word_wrap": true
-}
-```
-
-And here's what you'll get (With the awesome [Boxy Theme][] and its [Monokai Color Scheme][]):
-
-![MarkdownLivePreview Screenshoot](imgs/syntax-specific-settings.png)
-
-!!! tip
-    On Windows at least, you can press <kbd>alt</kbd> to focus (so show) the menus, even if they're
-    originally hidden.
-
-That's it! I hope you'll enjoy using this package! If it's the case, please let your friends know
-about it, and even myself by sending me a [tweet][] or staring the repo!
