General: changed local adc to voltage conversions in several places to use battery_voltage. Added battery_read_info function for unfiltered battery information. x5: removed adc_read as a distinct function. Removed adc tick task. adc_init is empty inline. Adjusted battery scale, voltage to level array and read 10 bits from the ADC for battery since 255 levels is not enough for true centivolt resolution.
