Remove redundant dicts for URL patterns and sidebar menu text, and use the
existing params dict instead. Add a sidebar_heading customization to params.
Better differentiate the 'User (self)' and 'Users' sidebar menus. Remove
the redundant Site settings menu items now that the Site entity is a singleton.
