Espruino on your watch!

It was programmed using OpenOCD - I messed up though and didn't manage to save the contents of the existing firmware!

Next steps, when I get time:

• Move the OLED driver into C code, save some Flash by removing the arraybuffer graphics
  
• Figure out how to use the over the air updates - I can't keep dismantling it every time I need to update the firmware :)
  
• Turn it back into a watch!
  
• Work out how the accelerometer is connected
