ok, tagtracker now tracks title, this has the disadvantage of needing to sort
the title tracker list, and it wastes more memory. But it makes implementing list command elegant, since we've just visit tags, then print out the visited tags in tag tracker (which has the benefit of making sure everything is in sorted order) git-svn-id: https://svn.musicpd.org/mpd/trunk@2608 09075e82-0dd4-0310-85a5-a0d7c8717e4f
