Robert Osfield 4a660f6266 Introduce new osgGA::Event and osgGA::EventHandler base classes that the old GUIEventAdapter and GUIEventHandler now subclass from.
The new osgGA::Event is written to support more generic events than the original GUIEventAdapter which are written for keyboard and mouse events.
