[ODE] air/water friction

[Tedd Streibel]

The air resistance force is proportional to the velocity squared, although
for a game environment I have found that using a force proportional to the
velocity (not squared) "feels" better.

You can do that by hand before calling worldStep.
calculate the drag and apply it at the center of the surface.
havent done it for spheres and cylinders. i guess there is a "closed
formula" for these primitives,
especially for spheres. Anyone, anyone?
