[ODE] contact joint problem

I didn't find anything about "rolling friction" and
"the difference between slipping and rolling" in ode
But I think, in my simulation, if I force the ball, it
would slip and it doesn't roll, because of force
vector direction.
Therefore, problem still exists: surface.mu is
infinity, but ball still rolls when forced.
Note that "bouncy" bit in surface.mode is set. (and
only that bit)
