Peter Barker 1208938d3b SITL: fix balancebot yaw reset to be kinimatically consistent 
... or at least closer to it.

We were hard-resetting the yaw to zero when the vehicle was upright.  That makes for huge simulated gyro rates, and that means the differences between the gyros can be huge sample-to-sample, so we can get gyros-inconsistent errors.

Fix things so we don't reset yaw at the same time as pitch, and also twist the vehicle to point North again when disarmed.

Peter Barker 84b3c9e267 SITL: reset balancebot to vertical in a kinmetically consistent manner 
The hard-reset of all state variables means we feed the EKF inconsistent gyro data.  Attempt to upright the vehicle with a simple p-gain when it is disarmed, as if someone is pushing the thing back upright
