added MavLink_TX & MAvlink_Tx_GPS_Rx to Revomini target
[STABILIZATION]: 1) Enhanced coordinated flight to include a yaw damper when
flying straight.
2) Added separate field for coordinated flight control gains.
[Coordinated Flight]: Removed bound from coordinated flight. Now the
vehicle will attempt to return to its original heading even in strong
winds.
