slight bug in category=security page

[=JeffH]

In this page..

<http://www.browserscope.org/?category=security&v=top>

..in the pop-up text for this column header -- "Strict Transport Security" --
there is a link to a very old very early draft version of the HSTS spec. Said
link ought to be updated to point at..

<https://tools.ietf.org/html/rfc6797>


thanks!
