RC_Channel_aux: added enable_out method to help stop servos from moving before the mount has initialised. 

changed parameter names of "update_aux_servo_function" to make it more clear that any 4 servos can be passed in (not just servos 5~8).
Also allowed NULL servos to be passed in as parameters because we only need 3 in ArduCopter.
