ActionMailbox conductor page for simulating email

[johnb]

I've just got a working demo up of ActionMailbox.

One thing that caught me out when I moved from dev to a Heroku + mailgun app was that with a real email (from gmail) it's a multipart message and you have to access the content differently in that case.

I know the conductor pages are probably still a work in progress but would it be worth them being able to simulate a multipart message?

Works pretty sweet though!
