save() on espruino_1v91.122_esp8266 results in immediate Disconnected prompt

Hi @Robin, the flash recipe you quoted above does not look right, for 1v91 it's...

*** To flash a 4MB esp8266 (e.g. esp-12) using the serial port use:
esptool.py --port [/dev/ttyUSB0|COM1] --baud 115200 write_flash \
  --flash_freq 80m --flash_mode qio --flash_size 32m \
  0x0000 "boot_v1.6.bin" 0x1000 espruino_esp8266_user1.bin \
  0x3FC000 esp_init_data_default.bin 0x37E000 blank.bin

Also, how do you know the flash recipe for travis builds? The link to travis binaries doesn't include any flash instructions?

Thanks
Rob
