[ODE] Changing the 3D coordinate system to left-handed

[Tobias Thorsen]

Isnt it just a matter of changing at which direction the gravity pulls?
I changed my system from right to left, and only updated my gravity vector -
everything looked right after that - also the collisions.
As far as i know ODE hasnt got any preference.
