Fix Django 1.3 compatibility

In the latest Django master code, RequestFactory.put behaves fundamentally differently than it did pre-1.5.  By default, it expects an octet string as opposed to a dictionary that it will encode like a multipart form.  So, for 1.5 and on, we have to be explicit about the multipart type and pre-encode the data.  However, pre-1.5 Django expects a dictionary if the content type is multipart.  So, the cleanest thing to do is explicitly handle the versions independently.

- Explicitly encode PUT data as multipart, as Django 1.5 no longer does so by default in the test client

Fixes for the documentation styles

Some minor docs fixes

Fix some typos.
Fix some indentation errors.

Implement simple token authentication

- All MockViews return Response objects
- Only one urlpatterns attribute in the module
- Renamed `RendererIntegrationTests` to `RendererEndToEndTests`, as the former wasn't being run locally (but it was on Travis...dunno).

The fixed positioning of the ToC needs to be overridden with static, so that the ToC falls back into the flow of content and is sized correctly. Also, this prevents the actual page content from riding up behind the ToC and being obscured.
