vzic Olson->iCalendar timezone converter update

Hi,

I've recently updated the vzic timezone converter and the new version
can be found at:

   http://www.dachaplin.dsl.pipex.com/vzic

So you might want to update the link on http://www.w3.org/2002/12/cal/


(The new version is basically the same version that was used to create
Evolution's timezone files, but tidied up a bit.)
