Dual-motor tailsitters

@tridge I’ve set the servo and Q params as recommended for the Stryker, performed accel cal and roll/pitch are reported correctly. Motors start when armed in QSTABILIZE, but elevon servos behave erratically for ELEVON_OUTPUT set to 0,1 and 2. They don’t move at all till I throttle up a bit; shouldn’t stabilization be working at all times? My CC Phoenix 25 ESCs didn’t respond at all to the ESC cal procedure, but they were flying OK on PX4 before.
