Minor IntroGame Bug Fix. This is a simple fix to a bug that caused the Pathfinding demo screen to update the wrong object. It happens when one skips the Pathfinding demo screen and then returns to it, the pointer we call the functions Update() and ToggleDrawPath( bool ) are different, causing the Planned path to never be drawn.
