Port to Tracker 3 + Song Editor dialog
(Based on the songeditor branch, depends on grilo-plugins!85 (merged))
Port everything to tracker3:
- All song metadata is fetched from the tracker-miner-fs service
- lastPlayed/playCount/favorite are stored in a local database at ~/.cache/gnome-music/db/
- playlists are all stored in that same local database
- grilo is used to store song metadata back
