A flag or report a comment feature

One more added feature before I go to sleep today. Now that I have turned on moderation of comments for all non-registered users, chances of spam and so on are fairly low, but in case some problem crops up you will notice a X link (if you're logged in) at the end of all forum topics as well as site-wide comments. If you see a problematic comment or forum topic, you can click that and flag it for a moderator (for the moment just me, but probably more in the near future) to look at. Please flag wisely though!
