Map Discogs "Unofficial Release" to MusicBrainz "Bootleg"
Map Discogs "Album", "EP" and "Mini-Album" and support secondary types separately from primary type
Add support for more specific CD/DVD formats (VCD, SVCD, CD+G, HDCD, DVD-Audio, DVD-Video, 8cm CD)
Update some format mappings: CDV is now available separately, Floppy Disk wasn't being correctly mapped to a format and Memory Stick is essentially equivalent to MusicBrainz's USB Flash Drive
mediums.i.position has been removed since it was originally never supported, so don't try seeding it
Check that a variable is set before trying to use it
Set unsafeWindow in a way which works in Opera
Map "Memory Stick" to "Other" instead, since after investigation it seems it's also used for SD cards
Revert "Check that a variable is set before trying to use it"
