Export all users columns

Like #2 I wanted this but with the dates formatted nicely. To achieve this I changed the _profile_csv_get_user function as follows:

function _profile_csv_get_user($uid) {
  $user = array();
  $fields = _profile_csv_users_selected_fields();
  //Verify that the columns haven't been deleted since the last save or the query will fail
  $schema = drupal_get_schema('users');
  foreach ($fields as $field_name => $value) {
    if (!$schema['fields'][$field_name]) {
      unset($fields[$field_name]);
    }
  }
  $cols = implode(', ', $fields);
  $result = db_query("SELECT $cols FROM {users} u WHERE u.uid = %d", $uid);
  while ($row = db_fetch_object($result)) {
    foreach ($fields as $col) {
      $user[$col] = ($col == 'data') ? unserialize($row->$col) : $row->$col;
      
      // Formatting the date
      if ($col == "created") {
      	$user[$col] = format_date($user[$col], 'custom', 'j M, Y', NULL);
      }

    }
  };
  return $user;
}
