Modified WiFi script to return mac address and to try to connect to cadre website using SJSU_Guest WiFi

FeatherWiFi.ino

/*
    This sketch sends data via HTTP GET requests to data.sparkfun.com service.

    You need to get streamId and privateKey at data.sparkfun.com and paste them
    below. Or just customize this script to talk to other HTTP servers.
