[Foundry 2] Allow objects creation in data provider

Maybe we could use lazyness behavior of the proxy system and delay persistence when the object is accessed

Yes, we should at least experiment with this before releasing 2.0 to ensure it's possible w/o a BC break.

cool! I'm just wondering if in any way, we could add a ->proxy() method to the PersistenceObjectFactory... because it will be one of the only usecase, I'd reallyl need proxies
