[ODE] Moving trimesh/trimesh collisions

[Erwin Coumans]

Novodex/Ageia and Havok don't support dynamic concave trimeshes.
Novodex has PMAPS (kind of signed distance maps I guess), but they told me 
they are mostly for non-realtime applications (like the XSI modeler, see 
http://www.edharriss.com/xsi/version5.htm).

My recommendation for real-time is an approximation using Convex shapes and 
Compounds.
