Esp8266 tutorial

I started a tutorial on how to flash the esp8266 with Espruino and, more importantly, how to use it without wires: connecting with the IDE over Wifi and updating the firmware over Wifi. Unless Gordon is willing to update the site soon, you will have to look at it on github:

• tutorial: https://github.com/tve/EspruinoDocs/blob/master/tutorials/ESP8266_Flashing.md
  
• esp8266 documentation page: https://github.com/tve/EspruinoDocs/blob/master/boards/EspruinoESP8266.md
  
  

I tested the various commands, but I'm sure I made mistakes and I'm also sure there are portions that are not understandable as written. Please let me know here (or in github issues) so I can improve the tutorial!
