Add support for music (#1059)

## Description
Adds support for music playback

### Features
- Adds a "Now Playing" page which is accessible from the nav drawer
while music is playing
- Manage the playback queue, add/remove/re-order songs
- Supports synced & non-synced lyrics
- Scroll through lyrics
- Click on line for synced lyrics to seek to that position

### User interface
- Customize what's shown on the "Now Playing" page
- Show album cover art, backdrops, and lyrics
- Show a basic bar visualizer
- Search for albums, artists, & songs
- Links between albums, artists, playlists, & music videos when metadata
is available
- Throughout the app, see which song is playing and which ones are in
the queue

Note: lyrics are synced by line. `10.11` added support for syncing by
word, but Wholphin still supports `10.10`
