Separate graphcool init and graphcool deploy

[schickling]

I suggest to semantically/functionally separate the graphcool init and the graphcool deploy command. This means that the init command just bootstraps a new project without actually deploying it yet.

That's a very good idea. I use graphcool init a lot just to boilerplate a local project, but without the need to deploy it, at least right away.
