[ODE] Trimesh vs Convex Hull

[Rodrigo Hernandez]

I have some ongoing work to that effect, you'll notice the functions for 
drawing convex hulls are already in the drawstuff library.
Currently, convex-sphere and convex-plane collision work, but I have had 
difficulties getting convex-convex collision working,
plus, its been a while since I even looked at the code, I've been 
thinking about commiting what I have into unstable, for 2 reasons,
the first one, because I think I am on the right track but short of 
time, someone may be able to lend a hand and the second,
because with all the revisions, it sometimes gets hard to bring my work 
up to date with the latest version on CVS/SVN.

So, what do you guys think? should I add the code already?
