Helper function that simplifies testing Django applications via setup.py
test
The idea is to test your application in a small test project. Since not
everything in your project is relevant (you don't want to test
django.contrib.auth gazillion times just because you use it in your
application) run_tests allows you to run just a subset of applications. By
default last item in INSTALLED_APPLICATIONS is tested. You can change it by
calling run_tests() with different argument. If you really want to test all
applications just pass None as test_last_n_apps.
