[watchface] bed time

I made a watchface! Tired with arguing the toss over how late is 'late' with my procrastinating children at bedtime, I made a watch face that simply says 'bed time' so I can switch to it and then ask them to read the time from my watch.

It's a bit basic. Barely more than a couple of tweaked pages from the dev tutorial. But it does the trick :)
