Csrf

As mentioned in https://github.com/OSU-Net/cyder/issues/421 and https://github.com/OSU-Net/cyder/issues/423
Refactoring all actions to use post data rather then url.
Attaching a csrf token to all post data.
TODO:
Fix tests related to views - they need to send post data
NOTE:
To test this, add 'django.middleware.csrf.CsrfViewMiddleware',
to local.py at the bottom of middleware classes
