[ODE] Duplicated vertices for trimeshes

[Geoff Carlton]

When I load a model I create a second copy of the vertex data, stripping 
off all data except for the position (originally it has normal & uv).  
Another reason to do this would be if the model is split by material 
into submodels.  At this point, it is possible to combine duplicate 
verts, eliminate them, and update the index list.  However, I haven't 
done this, and I don't think I'll need to - I can't imagine the 
performance impact would be that great to warrant it.

The problem is that, in order to render a mesh properly, some vertices must be duplicated because they have different U,V texture coordinates. But ODE/OPCODE doesn't need these duplicated vertices at all.
