[ODE] V0.8+ Bugs Update (Att: Bram)

dMassTranslate does the right thing to the inertia tensor in the mass 
description. The only problem is that the body doesn't pay attention to 
a non-zero delta off the origin. Now that we have "easy" geom offset 
matrices, perhaps we should re-enable dMassTranslate, and add some 
documentation about how you're supposed to offset the geoms to 
compensate for off-center mass.
