Add ModelWithFieldAttributes *before* PolyModel, so that everything does not
become a "ModelWithFieldAttributes" in the Datastore.
The way PolyModel works, each Model class hierarchy is stored in the Datastore
as the class that directly inherited from PolyModel. So, we do not want to
insert ModelWithFieldAttributes *after* PolyModel by inheriting *from*
PolyModel, or everything would just be a ModelWithFieldAttributes in the
Datastore, instead of Person, Work, Group, etc.
