Visually differentiate links that point to archived from those who doesn't

[GoogleCodeExporter]

It would be helpful to user, when viewing an archived page, to have a visual 
differentiation between links that point to archived pages from those who don't 
and that would open an error page saying "Resource not in archive".

There are several causes for the fact that links point to pages that were not 
archived but for users, that clicked in an archived page link, reaching a 
dead-end is frustrating and quickly adds up.

The idea is not to change the content of the original page but to identify, 
from the client-side, the links that would lead to a dead-end and visually 
identify them.

From original bug reporter: "One possible solution would be to identify the 
links to unarchived resources with a different color e/or a cross symbol".

This solution would visually differentiate the links but would change the 
aesthetics of the original page in the process.

Having tooltips on mouse over could provide the needed information without 
interfering with the aesthetics of the page.
