Tagging support per album, advanced organizational heirarchy

[zeekay]

Would like to be able to tag albums, genre, label, etc and sort by these tags. Could possibly scan all genres tags to create initial list of tags for collections. I think browsing by tag would be very nice, and additionally I think if given the option to hide the artist frame would dramatically speed up browsing. (An alphalist above the tags would handle that well, allowing you to still jump to a list of artists by name). On larger collections this is really nice, and loads faster for me (I removed the left frame and set a list of my root folders, which are all genre's anyways, as a sort of front page in main.jsp).
