Working pretty well with Jim's first cut at GAE app at
http://smartstatmicrosvr.appspot.com/SensorGraph.jsp
Added some delays after starting up WIZnet chip, and between
attempts to client.connect(). Also now checking the return
value from each connect and reporting an error to the terminal.
Works quite reliably when powered from PC USB, still doesn't
connect all the time when powered from 1A Asus tablet USB cube, which
seems odd.
