Version 0.2.3 - alpha release

Updated the Python FW uploader updated, it will now scan for the valves, allow selection of valves, scan for git hub releases and allow selection. Also will "verify" that values were posted correctly, and try to recover if needed.
FW changes include fix to properly allow VALVE ID remotely, this allows the uploader to find the new FW and flash all types of valves.
Fixes as well for issues with Auto blink light not stopping in many cases, even if SW dies.
