Summary: The Platform API is extended by a call to create the EffectsHandler. In X11 standalone Platform a new EffectsHandlerImplX11 is added which contains the X11 only parts of the EffectsHandler, such as grabbing the X keyboard and the X11 mouse interception window. The EffectsHandlerImpl gains some virtual methods for the parts which are now done in the X11 specific implementation. In return we get rid of lots of if-else structures checking for the operation mode. Test Plan: Only compile tested.
