Flip polarity

This switches the TCP server from the host machine over to the spark core machine making it easier to get started using AND to build up from the voodoospark firmware. To operate, issue one call to the spark cloud for the ip address ( curl "https://api.spark.io/v1/devices/{DEVICE_ID}/ipAddress?access_token={ACCESS_TOKEN}" ) and it returns the IP address and port that the service is hosted on (normally port 48879) and allows you to connect with any TCP client - including telnet - to manipulate the spark core.
