[ODE] Trimesh-Sphere inaccuracies

[ekt at libero.it]

i had the same problem in the past. someone said that
there should be no difference with small or big tris, so it 
was probabily a bug. my solution has been to find a good tris
average size (wich in my case is 3-5 unit per tris, ymmv)

another problem i've found is that, at low timestep (0.01)
a rolling sphere over a trimesh 'jumps' when crosses the edge
shared by two tris. probabily related to contact generated. 
timestep=0.005 solved the problem.
