[support] username.tpl.php and user_list.tpl.php

[Tamir Khason]

Default 4.7.2 installation. I want to change "Who's online" layout.
So, added overwrites to template.tpl.php
<?php
function phptemplate_user_list($items, $title = NULL) {
  return _phptemplate_callback('user_list', array('items' => $items,
'title' => $title));
}

function phptemplate_username($object) {
  /*if ($object->in_preview) {
      return theme_username($object);
  }*/
  return _phptemplate_callback('username', array('object' => $object));
}
?>

and two files username.tpl.php and user_list.tpl.php with what i want
to current thmplate directory. Reloaded phpthemplate engine by
accessing /admin/themes and reload it, but nothing changed. "Who's
online" looks exactly the same. What can be a problem?
