ADDED: #1471 new class CEventListener that can register with the NEl event server and then send the pumped events to a CInputHandler instance which ofc translates them to Nel GUI events and sends them to whoever listens. Also added a timer to NelGUIWidget which periodically pumps events and redraws the viewport.
