Fixed #4459 -- Added 'raw' argument to save method, to override any pre-save processing, and modified serializers to use a raw-save. This enables serialization of DateFields with auto_now/auto_now_add. Also modified serializers to invoke save() directly on the model baseclass, to avoid any (potentially order-dependent, data modifying) behavior in a custom save() method.
