Changed CAPTCHA method, hard banned some IPs

[vampirefrog]

Hi guys!

I've now changed the registration page CAPTCHA system with KeyCAPTCHA, which is a graphical puzzle sort of thing. To see it, try logging out and then going to the registration page. It's actually a fun toy )

I've also banned all the users that signed up in the recent period (164 sign-ups with some duplicate IPs), by using iptables. There are currently 131 such IPs banned on the mappinghell server.

Hopefully this should get rid of a lot of spammer bots.

Cheers!
