Add title tag to flag icon

I've added a title tag to the image to help users further. Very very simple change.

    if ($link['position'] != 'no_image') {
      $flag = '<img src="'. $link['src'] .'" width = "'. $link['flagwidth'] .'" height = "'. $link['flagheight'] .'" class="'. $classes .'" alt="'. $link['text'] .'" title="'. $link['text'] .'"/>';
    }
