[committed] wwwdocs: style: Remove link to validator.w3.org in footer

[Gerald Pfeifer]

Martin reported that the link to validator.w3.org we had on every page
(hidden in the footer) is not working any more.

This used to be a nice feature, where following that link "hidden" in
a full stop would validate the respective page. Alas due to abuse by
marketing tools and increased focus on privacy current browers do not
provide so called referer information anymore, breaking this use case.

Pushed, with a bit of sadness. And I reran the preprocesser on all (and 
checked some) web pages.
