esp8266: Add Python modules for initial configuration. Main entry point is _boot.py which checks whether FAT FS in flash mountable, and if so, mounts it. Otherwise, it checks if flash is empty, and if so, performs initial module setup: makes FAT FS, configures default AP name, etc. As a last option, if flash is not empty, and could not be mounted, it means filesystem corruption, and warning message with instructions is printed in an infinite loop. 2016-04-11 17:37:04 -04:00			`import uos`
