Small motion.em fix

[Will Monroe]

Hey everybody,

If you want to use motion.Collision, especially if you're planning on using the suspend/reset functions, you should replace your motion.em with this one (attached).  One of the changes I made that I thought only affected the documentation made suspend break and made me realize that I needed to do a few more things to correctly suspend and reset a collision controller with the new multipresencing optimizations.

A diff is also attached, if you want to apply the changes by hand (mostly for Behram and Ewen).

Cheers,

Will
