Added setting of osg_SimulationTime and osg_DeltaSimulationTime to the uniforms set by SceneView Added frame(double simulationTime) and advance(double simulationTime) parameters to osgViewer::SimpleViewer, Vewer and CompositeViewer. Updated various examples and Nodes to use SimulationTime where appropriate.
