Made Matrix be a typedef to either Matrixf or Matrixd. Defaults to Matrixf. Converted the osgGA::MatrixManipulators and osgProducer::Viewer/OsgCameraGroup across to using exclusively Matrixd for internal computations and passing betwen Manipulators, Producer and SceneView. Note, SceneView still uses Matrix internally so will depend on what is set as the default in include/osg/Matrix. Added the ability to osgProducer::setDone/getDone(), kept done() as the method that the viewer main loop uses for detecting the exit condition.
