 * The default value of 'permissionLevel' will now be false,

 * the default value set though (instead of false), so the
 * new JavaScript will interpret that as that the permission
 * level has been set specifically, instead of falling back
 * to the real (disabled) default value.
 * This code will basically detect if the page output is old,
 * and if so, re-calculate and correct what the values for
 * permissionLevel & defaultPermissionLevel.
 *
 * This section can be removed after July 7, because than the cache for all pages should be fine
