StandAlone Mode

I have tried launching this stack 5x todays following the instructions to a T. I have used this cloudformation script in other environments without a hitch. Right now, my exhibitor shows only 1 zk server and config says "unavailable". /v1/cluster/list shows {"servers":["unavailable"],"port":2181} and the logs show this:

Same problem here

I had the same problem when my EC2 instance didn't have a public IP, #10 should fix it
