Martin Gräßlin 3a8a0d73ea Save complete state in Compositing QObject
* all properties extended to be writable and emit change signals
* contains load from and save to config functionality
* Compositing object in qml view is connected to the values of the
  components. So changes are directly mapped from UI to business logic
