Re-enable PUT/POST/DELETE in the browsable api

Prefill form for instance view.

Instead of overriding the theme in the `extra_style` block, it can be replaced directly. This avoids having to load unnecessary styles.

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
