Disable COM_RC_IN_MODE magic handling, as its causing confusion on all autopilot stacks. This is a developer thing which is actually much easier to not expose, even for the involved developers.

Instead us a Toolbox concept which hangs off of QGCApplication

Also merged MissionController and MissionEditorController into single
MissionController implementation

Plus lots of other tweaks to ui for visuals

This is in preparation for full Qml main window

- select active vehicle
- arm/disarm
- select flight mode

removed the default firmware type for ArduPilot

also moved back to flashing stable firmware for 3dr radio

Also enable identification of clone 3dr radios

Too complicated supporting both modes as editor becomes more complex
