The new fields are:
ALBUM: mb_releasegroupid asin catalognum script language country albumstatus
media albumdisambig
TRACK: disctitle encoder
These are not yet parsed from MusicBrainz responses (just added to MediaFile
and the database).
Previously, there was just an "artist sort name" field -- now there's a
corresponding sort name for both track artists and album artists. I also made
the names shorter (artist_sort and albumartist_sort).
