Change VTOL Avatar from Quadcopter to Plane or new VTOL graphic

When MP identifies the aircraft as a VTOL it uses the Quadcopter graphic. Most VTOL aircraft look more like airplanes, spend most of their time as a Plane, and are based off the Arduplane code. The graphic should ideally be a new VTOL type, but in the meantime its better to display a plane.


Start by locating the Mission Planner code that selects the VTOL avatar and the existing Quadcopter and Plane graphics. Confirm how aircraft type is identified, then make VTOL display the Plane graphic or add the proposed VTOL graphic; done means the correct avatar appears for VTOL aircraft.
