Update Django Extensions version from 1.5.9 to 3.1.0
Update Django Extensions version from 1.5.9 to 3.1.0

Django Extensions 1.5.9 breaks on at least some functionality in Django
2.2. Specifically when you run `./manage.py cms show_urls`, you get:

```
  File "/edx/app/edxapp/venvs/edxapp/lib/python3.5/site-packages/django_extensions/management/commands/show_urls.py", line 9, in <module>
    from django.core.urlresolvers import RegexURLPattern, RegexURLResolver, LocaleRegexURLResolver
ImportError: No module named 'django.core.urlresolvers'
```

This PR upgrades to the latest version that supports Python 3.5
