Added the boilerplate code from the django docs to allow this to pick up...

... a csrf token for django integration.

I noticed when using this with https://github.com/pinax/phileo that phileo uses eldarion-ajax, but out of the box, causes a HTTP 403 error because the AJAX request isn't sent with a CSRF token.. 
So I added the boilerplate ajax code from https://docs.djangoproject.com/en/1.7/ref/contrib/csrf/#ajax

HTH.
