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

Finished merging QGCVehicleConfig.ui, which I hadn't done properly last night. Things are now in a usable state again.

Removing UASes now returns the UI to an almost pristine state. This was done by altering the activeUASSet signal so that it can emit a NULL UAS. Crashes may still exist in autopilot-specific code.

Changes go UASQuickView handles resizing better, and doesn't "clip" text when the window is too small.

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

Added satelliteCount to the QuickView, and made quickview a default display on the mission planner view.
