Initial rendering of Waypoints

- 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

More consistent with Qml usage pattern

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

Added "Advanced Settings" check box.

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.

Controls respect QGCPalette settings. Also added test window.
