This is all in the callback for collision: when you create contact 
joints, you need to specify friction and bounciness. The parameters are 
contact.surface.mu for friction and contact.surface.bounce for 
bounciness - set both of these to zero when your player geom's involved 
and you're done. :)

Oh - also, the mode flags (contact.surface.mode) shouldn't include 
dContactSoftCFM or collisions will be spongy and you'll sink into walls 
a little before bouncing back out.
