Title: Fixes #9. Handle SETTINGS_MODULE AssertionError

Django 1.4 has an override_settings helper. If you're using tower
and use the helper and don't override SETTINGS_MODULE, then tower
throws an AssertionError because there is no SETTINGS_MODULE in settings.

This fixes that and treats it like it would with an IOError.

Also, adds a test.
