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.
the functionality clear given the name. This will break user code unfortunately
so please be away of the following mapping.
osg::Matrix::makeTrans(..)?\026 -> osg::Matrix::makeTranslate(..)
osg::Matrix::makeRot(..)?\026 -> osg::Matrix::makeRotate(..)
osg::Matrix::trans(..)?\026 -> osg::Matrix::translate(..)
osg::Quat::makeRot(..)?\026 -> osg::Quat::makeRotate(..)
Also updated the rest of the OSG distribution to use the new names, and
have removed the old deprecated Matrix methods too.
