Implemented new security service to flag spam

There has been a significant increase in spam posts lately - enough that I'm finding it hard to keep up with and nearly impossible to stay ahead of... I can't ban users fast enough and even so they just come back with another ip and keep posting...

So - I've enabled spam protection from mollom which is an anti-spam service as an experimental step in fighting spam. I'll monitor it's effectiveness over the coming weeks and make sure it's not flagging too many posts as spam.
