Give your capistrano script some EngineYard config love

I was attempting to deploy the latest changes to the server for the very first time on my machine and got a wonderful little message from capistrano telling me:

`mongrel:restart' is only run for servers matching {:only=>{:mongrel=>true}, :roles=>:app}, but no servers matched

The fix? From what I understand is that you need to tell capistrano that your web and app roles are running mongrel like so:

role :web, '42.69.187.666', :mongrel => true
role :app, '42.69.187.666', :mongrel => true

That should do it for you, should you have this issue.
