Integrators and statistics

This release adds a new feature to the Windows control program – a statistics and integrators toolbox.
Statistics show average value, standard deviation, minimum and maximum for I, V, P and R.
Integrators count cumulative charge and dissipated energy, making it easy to measure ampere-hours and watt-hours.

Log file now includes system timestamp for every line.

Fixed multiple showing of error messages

This release fixes the issue when multiple error messages were displayed when the load could not exit fault state by disconnecting the device under test. Typically when the input voltage is too high.
Only one error message can be displayed at a time and it does not block the GUI thread.

Same principles have been applied also to the watchdog message.

Added automatic DAC reset

This should fix problems when DAC receives corrupted data.

Support for Arduino boards with larger ADC offset

Minor change: IADC_INTERCEPT is 16-bit signed now to support Arduino boards with larger offset.

Arduino Zero (M0/M0 Pro) compatibility

This release brings compatibility with Arduino Zero (M0/M0 Pro). The sketch was tested with Arduino.org version of the board, using Arduino.org IDE 1.7.10 with their bootloader.
