Removed getSurveyResponseFromPost from Surveys helper. We will use the power of Django Forms instead of getting our own properties. This fits better into the rest of Melange which also uses this approach.

    The given url may contain dict-style string formatting, which will be
    interpolated against the params in the URL.  For example, to redirect from
    ``/foo/<id>/`` to ``/bar/<id>/``, you could use the following URLconf::

        urlpatterns = patterns('',
            ('^foo/(?P<id>\d+)/$', 'django.views.generic.simple.redirect_to', {'url' : '/bar/%(id)s/'}),
        )

    If the given url is ``None``, a HttpResponseGone (410) will be issued.
