[IDEA] Display Album Artist, but sort by AlbumArtistSort

[apastuszak]

If the Artist/Album Artists lists was sorted by ArtistSort or AlbumArtistSort tags, then things like Billy Joel would show up under J instead of B, which is how record stores sort their albums, and how I prefer to have mine sorted. Bands get sorted by the first word after  articles such as the, an and a are removed, and solo artists are sorted by last name.
