Performance improvement

The ListView of MenuScreen doesn't hide Item's which are currently not on the screen. The logic has been improved to hide all Items which are not on the Screen and are not needed for a transition. In addition we make sure that the surface for the mapWidget is hidden once the HomeScreen is not visible.
