Minor tweaks and optimizations.
Added some admin interfaces, tweaked the default related name for the creator field in Entity, and added data generation through factory_boy.
Added username caching to BareUser and an index for comments.
Bug fixes: Fixed order_by in sequenced querysets and parsing in permissions.
Gave BareUsers special handling in the admin site and updated Permission's unicode method to be more descriptive.
Adding settings (minus sensitive information). Importing config.settings uses the local settings. If you want something else, you have to explicitly load it (e.g. config.settings.staging).
