Avoid erasing bottom widgets 

Turns out bottom widgets (specifically, digital clock widget)
were disappearing during maze generation. Still not clear _why_,
but calling `Bangle.drawWidgets()` from inside the `Maze` object
constructor solves this.

Also: say "Btn1" in order to be less confusing on `bangle.js 1`
(before I ask people to test this app on that platform).
