[bandcamp] Fix URL adding "name your price" downloads.

The logic checked for minimum_price > 0 and == 0 both, while they

[bandcamp] Fix URL adding "name your price" downloads.
New releases for all scripts.
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
Beatport Importer Userscript v1
This script currently supports importing;
* Release Title
* Release Label
* Release Catalog Number (if available)
* Release Date
* Tracklist
Updating date in @version to reflect actual completion date
Fix release date (use microdata date published)
Set default values for packaging, language and script

Most of stuffs imported from Bandcamp is eng/latin, and packaging should be None for digital releases.
Fix up free/paid download links

The matter is quite complex here, as Bandcamp is providing many options for the artist.
Mostly this should fix mixing up free download / paid download links in almost all cases.
