This makes VehicleComponents reusable from core plugin without
requiring override of prerequisiteSetup

There are many ways of iterating over lists in C++/Qt.
In the specific case of QStrings, it is known [1] that using
foreach with const references avoids the creation of new
QString objects in each iteration, reducing the time consumed
by the loops.

Refactored PX4 radio config to work with both PX4 and APM

Also turn on MavlinkLogTest

Instead us a Toolbox concept which hangs off of QGCApplication

This is in preparation for full Qml main window

- MultiVehicleManager is a Qml friendly replacement for UASManager
- Vehicle is a replacement for both UAS and AutoPilotPlugin

If Facts are referenced from FactPanelController, we need to reference
count the AutoPilotPlugin such that it doesn’t get destroyed until
after the FactPanelController is destroyed.

Also converted to new logging category

Allows for UI unit tests to be written:
- Ability to respond to expected message boxes
- Ability to fail test if unexpected message boxes occurs

This allows you to determine if full parameter list is ready if you
missed the parameterListUpToDate signal.
