Playlist queue patch (http://musicpd.org/mantis/view.php?id=1478) version 11.

This adds the following commands:
* queueid <id>		Add song <id> to the queue.
* dequeue <pos>		Remove song from <pos> from the queue
* queueinfo			List the queue

To the statusfield it adds the following entry:
playlistqueue:	<uid>		UID can be used by clients to track changes in the playlist queue.
