bad menu item similarnodes/build_cache

There's a dead menu item in this module that leaves you with a menu item with no title:

    $items[] = array (
      'path' => 'similarnodes/build_cache',
      'callback' => 'similarnodes_build_cache',
      'access' => true,
    );

Dunno why you'd want that in the menu anyway?
Anyway, adding either a title or a 'type' => MENU_CALLBACK fixes this.
