This has been an update to clean out the code a little bit. The primary change
I made was I added the method has_privilege (which takes a variable amount of
unicode privilege names as an argument) to the User model. This method allowed
for much cleaner checks as to whether or not a user has a privilege. Other-
wise, I also made it impossible for moderators to punish admins. I created a
new url path and three new pages for Users to look at filed reports and the
code of conduct for the mg instance.

=== Made reports on admins not resolvable by moderators:
--\   mediagoblin/moderation/views.py
--\   mediagoblin/templates/mediagoblin/moderation/report.html

=== Created new files for the new pages:
--\   mediagoblin/meta/__init__.py
--\   mediagoblin/meta/routing.py
--\   mediagoblin/meta/views.py
--\   mediagoblin/templates/mediagoblin/meta/code_of_conduct.html
--\   mediagoblin/templates/mediagoblin/meta/reports_details.html
--\   mediagoblin/templates/mediagoblin/meta/reports_panel.html
--\   mediagoblin/routing.py
--\   mediagoblin/static/css/base.css

=== Replaced vestigial methods of checking a user's privilege with the more
====== effective method has_privilege(u'privilege_name'):
--\   mediagoblin/db/models.py
--|   Added in the has_privilege method to the User class
