[ODE] Geomgroups vs composite

[Anders Olofsson]

Ok.. I'll stick to composite then, thanks!.

I have not tried 0.035 yet, the test_boxstack crashed for me when filling 
up the scene with composite objects (holding down the 'x' key will do the 
trick). In 0.03 that test works fine, is this a known problem?.

Cheers!
