Add Servo Output Message to Binary Protocol to Support HIL Simulation

[GoogleCodeExporter]

Right now on the ardupilot-mega side we are using the XPlane protocol for HIL. 
But it seems much easier to just define a new message for the binary protocol 
under the radio section that outputs the current servo positions. The servo 
positions can then be fed to the dynamics. The rest of the xplane protocol 
packets aren't required for HIL. On the arducopter side this would require 
updating the protocal.def file and regenerating the protocol.h file with awk 
for APM_BinComm.
