Add "note" or "important" class to the generated div.

The navigation header for the web pages lives in a different repository.
Read it during documentation regeneration to use the same navigation bar
on all pages.

Single-quoted strings are printed verbatim in perl.

make it use the website css and start structuring it so it is consistent

The generated HTML files are similar to the ones generated with
texi2html 1.56k used on the website.

Tested with texi2html 1.78 and 5.0. 1.78 is the minimal recommended
version.

The removed @sp from the titlepage section were ignored until
texi2html 5.0. If not removed the pages generated by 5.0 will have ugly
empty space around the title.
