[PATCH] Enable CsrfViewMiddleware -- make CSRF protection required by default

Hi list,

I noticed that most of the forms on the Postgres community site don't
use CSRF protection. That's bad -- CSRF should be on by default.

I went through all the views that handle POST data and didn't find any
that should handle input from cross-domain requests. But CSRF
exceptions, if any, should be decorated with @csrf_exempt (from
django.views.decorators.csrf).

Also available from my Github repo: https://github.com/intgr/pgweb
