Fix some links in the documentation.

(add missing @url{} commands, missing http:// prefixes, change
redirected URLs from http://tecnostats.net to their redirects
at http://riotorto.users.sourceforge.net.

There are some unresolvable links in Symmetries.texi (and translations).
(also with missing http:// prefixes, but the sites does not seem to
exist anymore).
Should we remove them? Or replace with links to archive.org?
