Upgrade to Django 1.11

[ajrbyers]

Upgrade to latest version of Django, this will require updating the django debug toolbar and updating dynamic sites to get rid of render_to_response.

This opportunity should be taken to upgrade all prerequisites.

/home/ajrbyers/.virtualenvs/janeway/src/dynamicsites/dynamicsites/middleware.py:
    3  from django.contrib.sites.models import Site
    4  from django.http import HttpResponsePermanentRedirect, Http404
    5: from django.shortcuts import render_to_response
    6  from django.utils.cache import patch_vary_headers
    7  from django.utils.http import urlquote
    .
  231                      if redirect_to:
  232                          cookies = response.cookies
  233:                         response = render_to_response(
  234                              'debug_toolbar/redirect.html',
  235                              {'redirect_to': redirect_to}

/home/ajrbyers/.virtualenvs/janeway/src/dynamicsites/dynamicsites/views.py:
    1  from django.http import Http404
    2: from django.shortcuts import render_to_response
    3  from django.template import RequestContext
    4  from django.contrib.sites.models import Site
    .
   16          'site':site
   17      }
   18:     return render_to_response('dynamicsites/site_info.html', args,
   19          context_instance=RequestContext(request))
