Subject: merge 3145-3146 from trunk Last (I hope) paranoic optims ... - move
 get_uysername and get_groupname from public to admin/functions.inc.php -
 optim in index.php - tags.tpl does not need smarty modifier included - move
 func get_comment_post_key from functions_comment to functions (avoid extra
 inclusion every time on picture page)
