http.get to Google Spreadsheet

Espruino won't redirect itself, but it's dead easy to add code for this. Try:

function getRedirect(url, callback) {
  require("http").get(url, function(res) {
    var contents = "";
    res.on('data', function(data) { contents += data; });
    res.on('close', function() { 
      if (res.statusCode==301 || res.statusCode==302) {
        console.log("Redirecting to "+res.headers.Location); 
        contents = ""; // free memory
        getRedirect(res.headers.Location, callback);
      } else
        callback(contents);
    });
  });
}

// espruino.com redirects to http://www.espruino.com
getRedirect("http://espruino.com", function(contents) { 
  console.log("Got:"+contents); 
});

Only thing I'd say is Espruino doesn't do HTTPS at the moment - the resources needed to handle SSL are really high for a microcontroller, and I haven't had time to try and shoehorn it in yet. It might be that the Google app redirects to an HTTPS URL, and won't accept non-secure connections. Not sure about that though.
