Throttle quadrant extension for Thrustmaster Hotas X for flight simulator

This Thing adds mixture and prop control, trim wheel and a few switches to the Hotas X flight sim joystick when used in split design (stick separated from thrust lever).
It´s considered work in progress, it may need some improvements (e.g. adjustable damping for the levers).
Thrim wheel can be implemented either as encoder or 10-turn potentiometer, depending on the electronics you use (i am using a Leo Bodnar 836 board)
