nobody seems to have objections...

* XHTML 1._0_. delivering xhtml 1.1 as text/html is bogus.
  (see <http://www.w3.org/TR/xhtml-media-types/#summary>)
* replaced the also bogus <dl> stuff by normal <p>s
  and added some CSS instead.
  (embedding CSS compatible to xml *and* html causes the very
  ugly hack, you can see in top.html, because in HTML <style> contains
  CDATA and in XHTML PCDATA, see also
  <http://lists.w3.org/Archives/Public/www-html/2002Apr/0053.html>)
* fixed some encoding issues.
* removed the weird empty lines at the beginning of every document
* added CONTENT_LANGUAGE parameter for pt-br
