Microbit build issues

I've just checked and I can connect fine over serial and Web Bluetooth and can upload code, for example:

var n=0;
setInterval(function() {
  n=(n+1)%5;
  show(1<<n);
},500);

However I do get the "setTimeZone" not found, and it seems if you're trying to upload a larger amount of code over Web Bluetooth then you get FIFO_FULL because Espruino was still busy trying to write the error message while code was being uploaded.

I've now added setTimeZone and if you use a cutting edge build now then the code should upload fine. Unfortunately things are getting extremely tight memory-wise in the micro:bit build now so it's always a bit of a struggle. I had to lower the space reserved for saved code this time as it seems it was overlapping with the actual program code.
