Login and logout views for the browsable API.

Add these to your root URLconf if you're using the browsable API and
your API requires authentication:

    urlpatterns = [
        ...
        url(r'^auth/', include('rest_framework.urls'))
    ]

You should make sure your authentication settings include `SessionAuthentication`.
