added board temperature calibration, warning and poweroff (rene-dev and me); rearranged config.h; fixed backwards beep overflow; removed duplicate battery-adc-code (rene-dev); improved battery voltage measurement precision; put poweroff procedure to a separate function; poweroff button now only work if field weakening is 0 (otherwise everything will explode)
