the regular Django dumpdata command now automatically works correctly
for polymorphic models and all Django versions
(this is handled by PolymorphicModelBase now).
Testing for dumpdata has been added.
instead of app-label and model-name (suggested by Ilya Semenov in issue 3).
This is a cleaner and more efficient solution, and applabel/modelname
are not stored redundantly in additional tables any more (the polymorphic models).
This should be the final DB schema now (sorry for any inconvenience).
Also some minor documentation updates.
