[ODE] Feedback for joint motors

[Peter Kyme]

Hi,

thanks for your thoughts. If I understand you correctly the force 
feedback for the dxJointLimitMotor is included with the feedback for 
parent joint. However I need the forces specifically applied by the 
motor, which I guess it not possible (as it stands).
