Fixes a minor indentation typo.

This allows subclassing TokenAuthentication and setting custom keyword,
thus allowing the Authorization header to be for example:

    Bearer 956e252a-513c-48c5-92dd-bfddc364e812

It doesn't change the behavior of TokenAuthentication itself,
it simply allows to reuse the logic of TokenAuthentication without
the need of copy pasting the class and changing one hardcoded string.

* Add a note about auth_token including Django migrations.

Added support for custom CSRF cookie names

Merge the changes in 3.3.x back to master.

Instead of hardcoding the CSRF cookie name, the value is passed to the template as a context variable, rendered as a JavaScript variable, and read by csrf.js.

Fixes #4048

* Made sure the OrderingFilter relies on Field.verbose_name.

* Marked OrderingFilter's order labels for translation.
