Formatting: Significant style cleanup in views.py. No functionality change
Fixed: Modified superfluous "/api" in some URL patterns

Those URLs in fact had nothing to do with any API. However, now I've freed the
/api URL-space, I can use it for calls straight into the WorkflowManager.
New: Update to Django 1.7
Fixed: Improper experiment detection is now proper

I forgot a hyphen, so the "intervals" experiment was always run. It's fixed.
Time for a new release.
