Subject: [PATCH] * _DetermineTarget() will now return fLastMouseMovedView in
 case there   was no valid "_view_token" in the mouse event. *
 _SanitizeMessage() will now only add the "be:transit" field for  
 B_MOUSE_MOVED messages. It will also now only update fLastMouseMovedView  
 for B_MOUSE_MOVED messages, and not for all mouse messages.
