Hapi Auth Basic implementation (can we simplify this...?)

[nelsonic]

I'm not a fan of how hapi-auth-basic
requires username & password to be sent to the server as:

{ authorisation : 'Basic ' + (new Buffer(username + ':' + password, 'utf8')).toString('base64') }

i.e. the front-end app has to base64 encode the un+:+pw and send it in the auth header.
see: http://git.io/xdjk

I would propose we _fork_ the module and create a second option:

payload: {
  email: "your@email.co",
  password: "5up3r53cr3t54uc3!"
}

Thereby allowing people to send the authentication POST request to /login with either the auth header _or_ a form payload.
