update Okabe-Ito URL to wayback machine link #21

The Okabe-Ito article URL was broken.

I converted this to a markdown-style link because the Wayback machine URL is long and ugly. This will be nice in HTML-format help but makes it disappear from text-format help, which you might not want ...

Thanks for finding the link on the wayback machine. I'm happy to merge as is.
