[ODE] Ground composed of cubes

[Jon Watte (ODE)]

Proper merging of near-coincident contacts is important in any collision 
handling code. If you get a collision at one edge, you'll also get a 
collision at the coincident edge on the neghboring cube. Merging these 
contacts (adding normals together and normalizing) ought to generate a 
flat normal for a single contact.

Cheers,
