Author email field

[leahneukirchen]

I mapped my Atom feed to JSON Feed, which was very straight forward, thanks for the spec! I hope it becomes a success.

I think it would be useful to allow mentioning a author url and email, so I'd propose to add an optional email string field to every author dictionary. I checked my blogroll, and while this feature is not used extensively, it's used occasionally.

This would make sense to me also. There is a separate Issue on multiple authors that might relate to this. #6

This could also be derived from going to the URL, but if people want an email parameter, it would be consistent.
