Move Notices category into alphabetical listing on user page

Without the weight on the notices category, Notices is listed first in the sub tabs on the user page (before Account settings). I think Account settings should always be first, so this moves it later in the list, in alphabetical order.

  switch ($op) {
    case 'categories':
      return array(array('name' => 'notices', 'title' => 'Notices', 'weight' => 1));
      break;
