This just mangles the library names for no good reason.

Restructured to better fit existing build structure

As this is no longer google specific, renamed everything google to qgc.

And name the target as the main app is now in its own sub project file.

- All resources are either under src or under resources dirs
- Removed files top level directory
- Move flightgear files to top level dir

New version using QtQuick along with an experimental Map Background

If it doesn’t exist it will be prefilled with all registered categories
set to false

Created new ScreenTools exported control for QML code to obtain screen DPI factor to be used for computing font point sizes. This code used to be in the tool bar code and now is available to all QML widgets.
Moved global mouse position tool into ScreenTools as I felt it would be a place to collect these sort of functionality.
Replaced Tree used in the Safety Component from a PNG file to a SVG file as the PNG was not scaling up properly.

Passing parameters QVariantMap across C++ boundary was causing crashes
in Qt due to Qml array bugs. Referencing same Fact* across Qml boundary
in multiple QQuickWidgets caused jScript GC to crash.

Shrunk the Message drop down dialog a bit.
Made the Message drop down dialog slightly transparent.

The goal of this first installment is to organize the code a bit so it's more readable,
clean up a bit of left over cruft, and manage link configurations (and links in general).

- Much simpler UI
- MVC style qml programming model

- Updated MainWindowTest to catch this problem
- Also implemented initial pass at SetupView unit test

Controls respect QGCPalette settings. Also added test window.

- Central widget no longer stacked. Views are added/removed to layout
to switch view
- Dock Widgets are globals with single instance of each type
- Both central views and dock widgets are just-in-time created saving
lots of memory
