Added view to process the test data

Added views to process the test data, the one at `website.views.trial`. Used the jquery.cookie library to read the `csrftoken` cookie and send it together with the POST request.

The URL to POST should have a trailing slash, otherwise the ajax request fails

The TrialResponse objects are created using bulk_create to speed up the insertion of the trials into the database

Also cleaned the settings file, removing settings with default values and extra comments
