[ODE] Some objects pass through other objects

[Keith Wiley]

More followup, but still without a solution.  dCollide always returns  
1 (or the occasional 0 when it misses a collision, but this is  
rare).  So even if more contact points are specified in the called to  
dCollide, it still only finds 1.  I think that once dCollide finds a  
contact point between two bodies, it doesn't look for any more  
contact points between those two bodies, but I need it to do exactly  
that, since multiple contact points are crucial to the ball sitting  
in the cup properly.  It will fall through any side of the cup that  
it doesn't detect a collision on.
