Move Cobalt configuration under Configuration and modules > System

In Drupal 7, it would be nice to have the "Cobalt configuration" menu item under Configuration and modules > System (or maybe Configuration and modules > Development). Currently it takes up space in the menu items at the first level, while the average user will seldomly want to change anything to Cobalt's configuration.

In cobalt_menu():

  $items['admin/config/system/cobalt'] = array(
    'title' => 'Cobalt',
    'description' => 'Settings for cobalt appearance and behaviour',
    'page callback' => 'drupal_get_form',
    'page arguments' => array('cobalt_settings'),
    'access arguments' => array('administer site configuration'),
    'file' => 'cobalt_admin.inc.php',
    'type' => MENU_NORMAL_ITEM,
    'weight' => 0,
  );
