Move googleimage search first, and enable it again but don't use eg filename in search query.
Move musicbrainz after last.fm, and don't try more than one way to find art, also do query once in 2 sec

If you get bad hits from googleimage album-art, please report them to me.

Conflicts:

	src/control/media_player.c

 - add an optional display callback,
 - make unlock callback optional (planes could be static),
 - pass an opaque picture identifier from lock to unlock and display
   callbacks (this would enable multiple pictures later),
 - pass pixel planes back to the unlock callback for convenience,
 - use pointer VLC variables instead of configuration strings,
 - fix an unlikely memory leak.
(cherry picked from commit b401af05)

Returns NULL if the variable cannot be inherited - pointers can never
be found in the configuration.
