Protocol: MT99xx (number 17)
Subprotocol: FY805 (number 4)
Supports headless and flip. For flip I'm not sure of the flag since it

Untested protocol...
Loads of changes:
STM32 board introduction: NOT TESTED
XMEGA renamed to ORANGE_TX to be more explicit
DSM: added reset if cyrf freezed
Validate: added a validate file to verify the different compilation
