See issue #429

I have just found a useful file in the ESP8266 core:

https://github.com/esp8266/Arduino/blob/master/cores/esp8266/core_esp8266_noniso.c

Has everything we could ever want in it...

There. No dodgy snprintf version any more. We now have a proper implementation lifted from ESP8266 (it's GPL'd, so that should be fine). We'll keep the original copyright intact.
