Title: Album Artist and Grouping field support

I've only tested this so far on GNU/Linux (Ubuntu 11.10) and with quite a limited sample of media files, but it's fairly straightforward stuff, after choosing a mapping from underlying tag fields. For that, I've gone for what seemed the best of the recommendations made by authors of other media applications, notably Picard.

Adding these fields may seem a bit iTunes-centric, but I've seen murmurings here and there about wanting this in TagLib, and, though support in other media applications and some tag formats is a bit piecemeal, they are fairly essential to any interested in encouraging migration from iTunes or side-by-side compatibility between it and their own application.

It might be worth considering a other mapping suggested in http://wiki.musicbrainz.org/Picard_Tag_Mapping

Thanks in advance for considering this pull request.
