* src/trackerd/tracker-daemon.c: 
	* src/trackerd/tracker-main.c: Put statistics update signal in a
	separate public function. Fixed not signalling stats when we
	remove a MMC. Now clients will get updates not only when an MMC is
	inserted. 

	* src/trackerd/tracker-daemon.h: Removed tracker_daemon_backup(),
	function no longer exists.
