Demo the UI with a dummy machine

This finally shows the basic operating principle of the machine UIs.
There will be some object out in the world that, when clicked, will open
a new UI screen to operate the machine.

Next up is to attach various bits of info, like a `Fuel` component on
the machine which the UI widget locates and displays as text. This gives
me the infrastructure necessary to begin that work.
