Base-class and default implementation of event-handler for TGLViewer.

This allows for complete disentanglement of GL-viewer from GUI event handling. Further, alternative event-handlers can easily be designed and set at run-time.

The signals about object being selected or hovered above are emitted via the TGLViewer itself.

The following rootrc settings influence the behaviour:

OpenGL.EventHandler.ViewerCentricControls:  1
OpenGL.EventHandler.ArrowKeyFactor:        -1.0
OpenGL.EventHandler.MouseDragFactor:       -1.0
OpenGL.EventHandler.MouseWheelFactor:      -1.0
