Return daap.songalbumid as a hash of the album_artist + album

iPhone remote will later want to query by album. Instead of doing a
fulltext query, it uses a 64-bit hash of the album + album_artist. It
is not necessary to use the same hash algorithm that iTunes uses. The
important thing is that we can later respond to a query=('daap.songalbumid:xxx')
with this value.
