YouTube™ Tracklist Control ruma Xavier Duthil

This extension builds its own interactive tracklist by scanning for timestamped tracks in the video description or comments.

The tracklist can accessed from any tab and controlled via keyboard shortcuts:
- Alt+I => Previous track
- Alt+O => Next track
- Alt+P => Play/pause

## Features
- Media control (play, pause, rewind, fast-forward, previous track, next track)
- Tracklist building from the video description or comments
- Tracklist navigation
- Progress bar on current song
- Support of keyboard shortcuts (see mapping above)
- Cross-tab interactivity (view and control the tracklist from any tab)

Notes: Due to regrettable Firefox limitations,
- The keyboard shortcuts are not global, which means that Firefox needs to be focused for the shortcuts to work (see https://bugzilla.mozilla.org/show_bug.cgi?id=1411795)
- The media keys can't be used (see https://bugzilla.mozilla.org/show_bug.cgi?id=1251795#c10)
- The shortcuts can not be remapped
