Added a honeypot field

Hi,

We had a requirement for a honeypot field from a client, so I’ve uploaded a version of your code to github (after checking the license) and added the feature. Would be great if you could merge into your repo.

The repo is here: https://github.com/surevine/contact-form-7

If you are unfamiliar with git along with git checkout URLs (right hand side near the bottom of the file table) you’ll notice you can check out my commits as SVN entries.

Thanks for this library, Lloyd.
