Send AUTHGROUPEX_GROUP setting to the authentication endpoint
Allow debugging without the fake endpoint
Rename test files for Django >= 1.6 compatibility

Django 1.6 introduced a new default test runner.  It now requires that
all files containing tests has a name prefixed by "test".

https://docs.djangoproject.com/en/dev/releases/1.6/#new-test-runner
Update Django version for Travis

https://www.djangoproject.com/download/ says:
* latest = 1.7
* previous = 1.6.5

Django >=1.7 is no longer compatible with Python 2.6.
Update URL in setup.py
Configure MIDDLEWARE_CLASSES in test settings

Django 1.7 complained:

(1_7.W001) MIDDLEWARE_CLASSES is not set.
    HINT: Django 1.7 changed the global defaults for the
    MIDDLEWARE_CLASSES.
    django.contrib.sessions.middleware.SessionMiddleware,
    django.contrib.auth.middleware.AuthenticationMiddleware, and
    django.contrib.messages.middleware.MessageMiddleware were removed
    from the defaults. If your project needs these middleware then you
    should configure this setting.

Set this setting to nothing to make Django happy.
Update django_authgroupex_dev settings to Django 1.7

This silences this warning when running "python manage.py test":

    Django 1.6 introduced a new default test runner. It looks like
    this project was generated using Django 1.5 or earlier. You should
    ensure your tests are all running & behaving as expected. See
    https://docs.djangoproject.com/en/dev/releases/1.6/#new-test-runner
    for more information.

cf. https://github.com/django/django/blob/1.7/django/core/checks/compatibility/django_1_6_0.py#L17
Make Travis test development site too
Use assertEqual instead of assertEquals in all tests

assertEquals is deprecated in Python3:
https://docs.python.org/3/library/unittest.html#deprecated-aliases
Add "email" to dev settings, to make test_fake pass
Force default settings for test_views

This test now succeeds when run with non-default settings.

Fix "python manage.py test"
