Administrative update - blog spam

The way that the commenting system is setup here, my hope is that you'll never see a spam message on this site. However, as of late Rotundus seems to be getting hit by about 50 comment spam per day. I have better things to do than read ads for casinos, drugs, and other such stuff.

A SPAM detection module should now be checking any anonymous comments but registered users should be exempt from this filter. If you notice any error messages popping up let me know. If you're finding the SPAM filter a nuisance ... then sign up for an account and use that instead.

Annoyingly this SPAM filter would only properly install after I manually checked all bracketing in 150KB of source code. (The original product seemed to like to use curly brackets as string delimiters in SQL statements which my database server didn't like.)
