Use Django's module loading rather than __import__

__import__ doesn't deal well with dotted paths, in my instance my root url conf is in a few levels "appname.config.urls". unfortunately, for __import__ this means that just `appname` is imported, but `config.urls` is loaded and no other modules in between are usable. Switching to Django's `import_string` method allows importing the final module in the path string, in my case the equivalent would be `from appname.config import urls`.
