Running make linkcheck in the website doc pages turns up a bunch of
broken issues.

Some of them are url's that are examples and not expected to resolve
(e.g. http://myroundup, http://localhost etc.).

But there are a number where it looks like the resource has gone.
Some of these may need to remain broken (e.g. the zope link in
COPYING.txt since it's a verbatim quote in the license).  The rest
need to replace/remove old references and update the pages to point to
a new url..

I can't do this before the 1.6 release so recording here for others to
work on.

List of broken links and the doc files and locations in the 1.6
release tree:

Fixed them and checked in and deployed to web site.

Some references removed (gmane and nabble archives), some 
internationalization tools updated (KBabble is obsolete)
