[ODE] AMOTOR

[Jon Watte (ODE)]

AMotor is just another joint. Some joints (like Hinge) can emulate the 
AMotor behavior, and additionally introduce a position constraint (which 
AMotor doesn't).

It's cheaper to use one joint (hinge with dParamVel) than to use one 
joint and one amotor, because it uses fewer constraint rows in the 
solver matrix.
