deis 1.0.2 (new formula)

Deis recently reached a production ready 1.0 product. It will be nice to have the client utility in Homebrew.
I don't think the Deis client can do much without first registering to a cluster with `deis register`. The only other command that seems to exit 0 every time is `deis logout`. But I'll poke around for a better test.
