Update to the security system. It is now possible to have users with only certain permissions on certain PIs. For this each PI is now associated a VIEW, EDIT, CREATE, DELETE, and UNDELETE role. SecurityHelper.php was updated to provide a default permissions setup for newly created objects. All controllers were updated. Load the fixtures data.
Removed old stuff of Fernando's security implementation.
Elegant way of adding asterisks to required fields by form theming.
