Adds and/or modifies link and image title attributes to include more informaton
当前为
FireFox shows a link's title as a tooltip when hovered over, but nothing if there is no title given, or just an "alt" attribute for an enclosed image. This script ensures there is a title and includes the target location in parenthesis.
