* Highly experimental ODE_STEPSIZE = 0.025f - 1000 / 25 = 40fps - 10 substeps with fallback to 5 substeps when things get slow

* Just to give you an idea of the difference ..    previous ODE_STEPSIZE was 0.005f - 1000/5 = 200fps - 10 substeps with fallback to 5 substeps when things get slow
* *nix avatar may fall over again, *sorry*
