Some things, like CSRF protection (#361), benefit from the ability to uniformly call helpers before and after a request is processed by the view. In the case of CSRF, we want to confirm that the token matches before processing the view, and make sure the token is set before delivering the response. Unlike WSGI middleware, this sort of wrapping is an integral part of the application.

A few tickets are blocking on being able to rip test data into the database, and some giant put me on his shoulders and then I saw the promised land of test fixtures. We need to support test fixtures.

As I don't have any simple way to test cloud storage, I'm filing this as a bug.

1. StorageObjectWrapper should have a close() method
2. process_media/__init__.py should use the real closing() function from contextlib instead of the current dummy one.

I would also suggest to rename StorageObjectWrapper to include something about CloudFiles.
