This patch ports the ampache, magnatune and opmldirectory services. I've laid some groundwork for the other services too, but they still have problems. For example: Jamendo has changed its API, which makes the service useless in its current form or the gpodder service using mygpo-qt, which is still in a qt4 world and therefore makes amarok crash when used. Mp3tunes and lastfm don't work either, but I haven't yet investigated why.
