Extends the AddonManager API with two new methods, setWebExports and
getWebExports. setWebExports expects an add-on module name and a
valid RegEx pattern to match subpaths in the add-on folder against.
Any matching subpaths will be accessible in Anki's web views by
referencing them with /_addons/{addon_id}/{subpath}.
For instance, to allow access to .css and .png files in your add-on's
user_files directory you would call:
> mw.addonManager.setWebExports(__name__, r"user_files/.+(\.png|\.css)")
You could then reference these files in web views as such:
> <img src="/_addons/{addon_id}/user_files/test.png">
Please note that this bypasses the default security policies used
in Anki webviews. You should take care to construct your RegEx
patterns specific enough so that they do not match any sensitive
files of our add-on.
