kOS (and other attitude PID controllers) support #12
Description
Currently, when using the kOS PID controller (or any other PID controller that disable the stock SAS), reaction wheels are stuck in the "nerfed torque mode".
It should be possible to read the angle error from kOS to apply the nerf in the same way as for the stock SAS. This said, the kOS PID controller can become quite unstable when feeding it with large torque variations. This require more testing.
Other PID controllers (MechJeb, TCA...) could also benefit from specific support.
