Offload Registration/User Auth to Passport.js

[Immortalin]

Users should not be doing password hashing, registration stuff etc. by hand. Node.js already has really good support in the form of passport.js. The equivalents in other frameworks are Devise and Django-allauth.

It should be possible to use any Node modules such as passport directly from Macchiato. I'd be open to a registration/auth wrapper library based on Passport.js.
