Update gen_contrib.py to match current contributors.py

Now `manage.py gen_contrib` generates a contributors.py matching the
already existing format. It normalizes names to make the list more
enjoyable.

Before using this to seriously generate contributors.py we need to
figure out a way to add pseudo names, or tell everyone to change their
name on GitLab.
