Toggle to show just comments that have links
Adds an item to the hacknews menu called "LinksOnly"
which shows you how many links are found in the comment
section for an entry and when clicked, toggles hiding
comments that don't have links embedded in them.
Other things it does:
*)changes default sorting for search to "By Date"
*) makes all links in comments and links to articles
on the front page open in a new tab.
*) highlites links in yellow and visited links in pink
