Initial implementation of QML Palette support

Delete unused files

No longer needed with move to summary page qml

Vehicle Summary is now QML

Summary page is also the launching spot for the setup screens. No more
left hand set of buttons.

This prevents mavlink signals from being emitted after link is
disconnected

When using DeleteOnClose with a QQuickWidget, the shutdown sequence
causes the MainWindow destructor loop back onto itself.

- properties now hand off of main “autopilot” object in qml
- Added support for summary items through qml
