The now-playing bar, MPRIS metadata, and the desktop notification showed
the clean album name; for a re-edition (e.g. Octavarium (2009 Remaster))
the variant was lost. Carry the album-level version on QueueTrack
(populated on the album-play path) and append it to the displayed album.
Last.fm scrobbling keeps the CLEAN album name so editions don't fragment
stats. New album_version field defaults to None on every other queue source.
