KitchenPi: adding a watchdog

Although KitchenPi has been running well for over two and a half years, I do get the occasional blip.

A recent issue caused the system to fall silent.

But this turned into an opportunity to do a couple of simple software modifications.

Although the power drawn by the RaspberryPi is very low for a computer, its still significant for battery powered equipment such as my bird box monitor.

So here is an idea to reduce power consumption during periods of inactivity.

During the early weeks of the nesting season, visits by birds to garden nest boxes may be infrequent. Typically here in southern England, garden birds may start checking out nest sites during February, with more activity running into April, when nest building typically gets under way.
