Title: Nirvana eventhandling 40

Eventhandling like we had it with OSG.
* EventHandler, receives events first, handles top-level events like ESC, reload, pausing etc. Pipes other events to Navigation & Manipulator.
* Navigation, nearly like our OSG navigation.
* Manipulator, able to manipulate/inteact with World.
