Split the Lumina 2 backend:

Based on a qmake flag, have it use QtWidgets or QML for the front-end renderer.
This will allow us to import/use all the Lumina 1.x interface elements (in Widget form) for now, but switch over to QML interface later without losing all the improvements to the underling events/communication systems.
