New features and WA for wifi problems
New features and WA for wifi problems

Added new sensors, two temperature (DS) for measuring temperature
inside the box and one for outside temperature.

Added also measuring of light conditions.

To tackle weird "jamming" issues related to esp-05, added forced
restart of esp, every 12h. Let's see if that helps (has now been
working for over 24h).
