Increased max pitch/roll angle and maximum output from rate controllers. removed comment from log file being dumped.

Some rough updates to the model to reflect previously unmodeled behavior in the IMU and the alternative of using the camera system directly for pitch and roll.

Allowed values to be set before Gear switch. Re-enabled x/y controllers and made throttle manual for autonomous mode.
