A Chef recipe for ProFTPD

I needed to deploy an anonymous FTP server, and of course I wanted to do it using Chef, so I went looking for a Chef recipe to install ProFTPD. Sadly, the lazyweb failed me. So, I did some actual work so the lazyweb won't fail you. :)

Here is the commit that adds a ProFTPD Chef recipe to my fork of the ey-cloud-recipes repo. Enjoy!
