[ODE] small sized capsule on heightmap problem

[Jon Watte (ODE)]

The terrain is infinitely thin. This means that objects can tunnel 
through terrain, if they move quickly in a single time step. The 
solution is to make the objects bigger, to take much smaller time steps, 
or to do some kind of continuous collision (like casting a ray or 
capsule between old and new position each step).
