Burning BPI:bit webduino firmware in Windows system

A special Webduino version have been developed for bpi:bit. Of course, before using it, we need to program bpi:bit flash with the Webduino firmware.

Note: bpi:bit has been programmed Webduino firmware by default. Only when you reprogram the flash with other firmware, will you need to program Webduino firmware again.
