Install configuration message

Thanks to russel.dk review: http://drupal.org/node/1637450#comment-6165526

When the module is installed, it would be nice with a message showing that it did so. The message could link to the configure page. Here is the code I used for my module, which is also in the application queue:

/**
 * Implements hook_install().
 */
function webmaster_menu_install() {
  // Tell user that the module was installed and how to configure it.
  $t = get_t();
  $link = l($t('Administration > Configuration > Webmaster menu'), 'admin/config/webmaster_menu');
  $text = $t("Webmaster menu was installed. It can be configured here: " . $link);
  drupal_set_message(filter_xss_admin($text));
}

Note that you should not use get_t() here. Not t() and not st() (see http://drupal.org/node/1420358#comment-6099242)
