Before, it could be instantiated after an engine loaded and then was never deleted, causing memory fragmentation. Also removed inner tooltip call to the GuiManager runloop, which makes the logic simpler since the tooltip is a bit of a hack. I had to remove it because deleting _tooltip in the inner loop (called from tooltip itself) is trouble. svn-id: r54311
