DCM: separate out the omega_yaw_P from omega_P
...
this cleans up the separation of drift rates and proportional
correction from yaw source and accelerometers, allow the yaw
to run at a different rate to the accel correction

Quaternion: fix the gyro bias in centripetal and remove smoothing
...
the centripetal code needs to take account of the current gyro
bias.
It turned out that the accel and gyro smoothing was causing
significant control lag, and we're better off just letting the
quaternion code handle it via its own smoothing parameters
