Captcha for Drupal

The Captcha module for Drupal version 3.0 RC1 has been released. It's a complete redesign and I'm happy with how it worked out. Big thanks goto soxofaan, Heine and wundo for helping putting this all together. I updated reCAPTCHA to use the new Captcha 3.0 API, and hopefully it will be much more stable now.
