Self-made template to generate navigational links.

Changed the output format from table to ul.
Placed the same links on both header and footer.
Added a title attribute to the link containing the target title
(it content is displayed when placing the mouse over the link)
For "Prev" and "Next" links, added the target title under it.
When "Next" target is the Index, added gentext support for the
Index title.
