work around collide not returning false with a nul object

Browse source 
fix a crash caused by having boundingBoxCollision on, while projecting the mouse so that there is nothing between it and a globalbounds object
it would seem we're somehow ending up in a state of WorldEditor::collide returning true it hit somethging, but NULL as far as *what*
until we properly fix this, doublecheck to make sure the hitObject isn't NULL before we start trying to reference membervars/methods
