Request based filtering?

[AndreiPashkin]

The FilterSet may be initialized with an optional request argument. If a request object is passed, then you may access the request during filtering. This allows you to filter by properties on the request, such as the currently logged-in user or the Accepts-Languages header.

It seems like this feature is not supported. I thing it's a good idea to introduce it.

Fixing this should be fairly straightforward:

• The backend needs to initialize the filterset with the request
• The related filtersets need to be initialized with the parent's filterset
• Tests should demonstrate failure for the main filterset and related filtersets

I'm currently in the process of refactoring some of the internals - this will be included as part of that.
