Objects with FileFields no longer get save() called multiple times from the AutomaticManipulator! This fixes #639, #572, and likely others I don't know of.

This may be slightly backwards-incompatible: if you've been relying on the multiple-save behavior (why?), then you'll no longer see that happen.
