Deprecate RequestFactory

[robhudson]

Django 1.4 added wsgi.input so this can now point to Django's or be deprecated.

Deprecate... in fact I don't even see the use for most of the things in this repository. I'd almost say if there is anything useful, just merge it into playdoh

[robhudson]

I agree, actually. I'm trying to get zamboni off of test_utils. The Fast Fixture thing is in django-nose which we can use and the few things that are left for us can be added to our base test class -- things like setting the cache timeout to -1, etc.

[jsocol]

+1 for deprecating this whole package but not necessarily to playdoh. If there are things that are more generic but nose-specific they could go into django-nose

I feel like when @robhudson with deprecating (or heck just remove them and bump the version number) there won't be much left.
