Latest Espruino build for Esp8266

I still see new folks start with esp-01 modules, FWIW.

Yeah, I'd say that with Telnet support the ESP01 modules are still pretty relevant.

There must still be some easyish ways to get the code size down? There are ifdefs in the Math lib for cutting down on code size (with small but slow implementations of trig functions). And has anyone run find_big_rom.sh in the .lst file? That's my first stop on ARM.
