Improved stability of analog signals in the Arduino sketch

Reimplemented automatic refresh of the serial port list
Improved serial device connection retry
Moved plugins to their own subfolder for better separation, added metadata on the entry assembly to load
Added logging settings
Added Run at startup setting
Many visual enhancements
