From Chuck Seberino, "Here is a small optimization in osgDB/Serializer that only uses a single accessor call when retrieving serializable values during writing. This is a sizable win for some of my code since the getter() methods are non-trivial. I also removed some explicit namespace qualifiers to be consistent with the rest of the codebase."
