Jocelyn Fiat bba1d57ce3 Fixed and improved various issue in admin module (especially the Role editing which was not working as expected.)
Added CMS_MODULE.permissions to allow module to declare the potential permissions.
Added support for CMS_LINK.is_forbidden, in relation with CMS_LOCAL_LINK.permission_arguments.
Split link "username (Logout)" into 2 links "username" and "logout".
Fixed/Changed the way auth modules alter the logout link based on "(Logout)" title, by safer solution based on `location' of the link.

Fixed usage of WSF_REQUEST.path_info by using percent_encoded_path_info which is not non unicode path info to be used most of the time.
Merged CMS_REPONSE.variables and CMS_REPONSE.values .
When possible, prefer usage of CMS_RESPONSE.user instead of CMS_REQUEST_UTIL.current_user (WSF_REQUEST) whenever it is possible.
When possible, prefer usage of CMS_RESPONSE.location, rather than usage of WSF_REQUEST.(percent_encoded_)path_info .
Code cleaning.
