Eugene Yokota 0e8459ad66 Better error message if socket is taken ...

We need to communicate the error states in the thread, so I added a `Future[Unit]` called `ready`.

If something goes wrong during the startup, like if the port is already taken, this can be used to communicate back to the main thread, and display the error accordingly.
