I am starting to get kinda pissed off with the comment spam on my wiki. It's time to fight back!

At the moment we have confirmEdit, which is great for stopping links being automatically inserted, and
stopping spammers from automatically creating accounts, but turning it on for every edit it bit too high a
barrier. And we have $wgEnableSorbs, which is great for stopping open proxies.

But there is a new category of wiki comment spam emerging, one that adds random gibberish to your wiki,
without any web links, and that is often not a known open proxy. It adds words like "laletoalca" and
"rolerr" and "notac4tc" and "virochiorboa" and "oloreldell" and "c4teltlir". (What the fuck does that
even mean, and why would anyone bother writing a bot to add it?!) Maybe the idea is to then add links later - I
don't know, but it is annoying, and from my perspective the incidence of this seems to be steadily escalating.

So this extension takes it one level further, whilst still allowing anon edits, as it asks the Project
HoneyPot DNSBL whether an IP address corresponds to a known "comment spammer" (which is a new category
they seem to have added recently). The reason I selected honeypot rather than another black list is that
for the last batch of spam comments that got through on my wiki, they were all listed as "comment spammers"
on honeypot, and usually within the first 10 Google hits for those IP addresses. (i.e. based purely on past performance).

Extension considered totally experimental. Use at own risk. Requires a honeypot key to use. Steps to get this:
* Create an account - http://www.projecthoneypot.org/create_account.php
* Verify your account by visiting the emailed URL.
* Create a key - I think the URL is: http://www.projecthoneypot.org/httpbl_configure.php
* Then add to your LocalSettings.php, add:
