Add a custom banner to Mezzanine's runserver command, showing a logo and various software versions.
Handle new management command loading order in Django 1.7, so we can override runserver.
Make the setuptools test runner part of the mezzanine package so that we can call it from other packages (such as cartridge). Also make its local_settings module more dynamic.
Remove working directory hack from bundled manage.py - conflicts with Django runserver's auto-reloader when run from outside of project root.
Updated development instructions for setting up Mezzanine when contributing.
