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

Quaternion: use GPS to correct for linear acceleration
...
this gives much better pitch estimates. We should do this with the
airspeed sensor if available.

Quaternion: don't update if we have a very long deltat
...
this can be caused by stopping the system in a debugger

Quaternion: added an AP_Quaternion library
...
this is for experimenting with the Madgwick quaternion system, to see
if it is more or less noise sensitive than DCM
