title: django-nose testrunner doesn't use --with-django option
body: <p>When running nosetests, django-nose runner doesn't supply <code>--with-django</code> option to <code>nosetests</code>, so my nose + Twill tests fail when trying to access URLs:</p>
  
  <pre><code>./manage.py test
  ...
  raise BrowserStateError("cannot go to '%s'" % (url,))
  BrowserStateError: cannot go to 'http://127.0.0.1:8088/admin/'

  <p>When I supply <code>--with-django</code> manually or set <code>NOSE_WITH_DJANGO=1</code> enviromental variable, my tests run successfully, but then I receive following exception:</p>
  
  <pre><code>$ ./manage.py test --with-django
  ...
