Fixed the lag with Follow Path and optimized constraint loops with Track To and Lock Track. I was plainly disabling the refresh of the target, but that caused a lag (3D window, not Render). Now, it raises a flag when it find a loop, so it only disables the refreshing when it needs to.

This is a temporary fix, but a complete fix will require a rewrite of of some part of the where_is_object function, and that would take too much time before 2.31.
