Out-of-order cleanup errors

[GoogleCodeExporter]

In a project, set up a motion so that an object begins moving but doesn't stop 
on its own

Now preview that project, and once the object starts moving, the Stop Preview 
button will not work.

Updated summary with actual bug causing symptoms:
When world cleanup gets called, models are cleaning up (and clearing out their 
transforms) before motions that rely on those transforms clean up.

Another bug was compounding to cause this issue:
Motions were not cleaning up properly when multiple motions were stacked on the 
same transform.

Fixed with latest commit. Motions should now clean up in a more dependable 
manner. They also subscribe to the Model's cleanup message and clean themselves 
up first.
