Docker Private Beta (OSX) first look

Initial improvements:

Every terminal session is now auto-configured

Before: every single time you started a new terminal session, you needed to run the following:

eval “$(docker-machine env)”

Now: Nothing — it just works every time, in every session :)

`docker ps` will now report the docker IP when listing any addresses

Before: You needed to know your docker-machine IP address & then append the port to it. (via `docker-machine ip`, or `env` etc)

Now: The correct IP is right there in the `docker ps` command. :heart: — this means access to your services are a copy/paste away

Previously, we would of seen here

Updating as I discover more. (looking for fixes re: permissions, volumes etc)
