Latest Espruino build for Esp8266

After more than a week without a build here's finally a new one :-): http://s3.voneicken.com/espruino/espruino_1v84.tve_master_363580f_esp8266.tgz

Changes:

• Changes to 160Mhz for a bit of a performance boost
  
• Changes I2C timing to just under 400khz
  
• Fixes hardware SPI (SPI1 device), baud rate is selectable from ~100khz to 4Mhz, default is 100kHz
  
• Includes save area compression
  
• OneWire select() always resets the bus first (it's required)
