Add new parameters to views: url_name which is name used in urls (instead of using lower entity names) and module_name which is used for constructing django urls. Append changes to all affected files. Fix some title names. Change urls that included underscores like "site_settings" into urls with slash "site/settings". Plus some other minor fixes.
