external-app-launcher di David

This addon has a single function: to forward certain URLs to an external API, which should be in charge of launching an external program.
The default configuration will

Block .googlevideo.com/videoplayback (to prevent playback within the browser)
Forward https://www.youtube.com/watch?v (for remote playback)
There's an example http server packaged with the extension that launches mpv on the urls it receives, it can be extended to handle PDFs, etc.
