[ODE] Problem with rolling

[Jon Watte (ODE)]

It has been my experience that Euler angles are almost never a good 
idea. Typically, just keeping a quaternion is more convenient.

The one time when Euler-like angles are useful, is when controlling
things from the mouse (like a first-person camera) where you can map the 
controller input directly to Euler angle values, and then convert to 
quaternion each frame.
