   This needs a change in backend templates 2k11/admin/entries.inc.tpl

   and fix a wrong set config value

   as long as the Browsers SESSION holds
 * Posted sidebar lang selection influences backend lang ... document dependencies
 * Fix 'enry_title' Smarty var not using translation with Smarty3 versions in
