Script Summary: Inserts a WHOIS link next to each anon IP on Wikipedia sites
If you need the IE7 version, please see http://www.iescripts.org/view-scripts-189p1.htm
Current Version 1.4 - Changed IP regex to match on octets of 0.
Version 1.3 - Filters out external links. I noticed that certain articles contain text similar to IPs' (eg: anything that has an Enzyme Commission code). If the href doesn't link to Wikipedia, we don't want a WHOIS for it.
Version 1.2 - Fixed Special Contribs links (when text was shown as textContent)
Version 1.1 - Fixed a bug with User talk links. Shouldn't include text in URL now.
