[ODE] air friction

[George Birbilis]

if ODE doesn't support air friction as is (3impact which is written on top
of ODE does, so maybe ODE does too, check the API headers and docs for it),
at every time step set a force that is at the negative direction of the
movement and a torque that is at the negative (angular) direction of the
ball rotation

those forces need to be analogous to the respective speeds I think, with a
low speed limit above which the force starts working and a high speed limit
above which the movement/rotation opposing force doesn't increase anymore

but maybe this is too much simplified
