Message:

• use the VorbisComment style tag names in the info hash returned by MusicBrainz::get_musicbrainz_info()
• use the MusicBrainz name credit join phrase to build the string where there are multiple artists
• include the artist sort names in the returned info, as TRACKnn.ARTISTSORT keys, and ALBUMARTIST
• added an applymeta script that applies the metadata listed in a file to a set of MP3 files
• when loooking up a release, MusicBrainz::get_musicbrainz_info() prints the number of releases and some other debugging info to STDERR
