Add ability to specify artist or album

[chowbok]

I could be wrong, but currently there doesn't seem to be a way to play an album if an artist has the same name. For instance, I can't play the Siouxsie & the Banshees album "Kaleidoscope" because I also have several albums by the band Kaleidoscope. I'd like to be able to say "play album Kaleidoscope".

If the new fuzzy matching works ok, I'll extend it to cover these cases as well.
