Update to Hapi 6

Hapi 6 has some cool new feature that can enable this project to be more modular. I think it should be considered.

Im thinking that all of the assets we use like stripe, nodemailer, parse could be make as plugins.

var stripe = request.server.plugins.stripe;

To avoid any name spacing issues that may occur on the by directly adding it to the request object.
