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

Replace 9 seperate valueChanged() signals with just 1, and remove the resultant tons of code duplication

Change so UASQuickView font sizes are now identical, and change properly based on window size and column count

Some comment cleanup, and fix so when closing the main window, it also closes the item select window

Fix for crash when removing item from QuickView, and addition of more generic signal/slot combonation for property updates
