From Wang Rui, "I modified the Serializer header to add a UPDATE_TO_VERSION_SCOPED

macro, which could set version within brackets and reset it after
that. All related serializers are also modified so that the
backward-compatibility bug reported by Farshid can be fixed.
"

From Robert Osfield, removed the use of osg::Referenced and creating the proxy object on the heap.
