Implement the logic for sending one word at a time to each boy

And for the boy's devices to fade each word out.

We're cueing off the first letter of each boy's name to ensure they
end up in different rooms. (So if people join the game with a name
whose first letter is other than 'C', 'H', 'A', or 'S' they will be
put into a random room.)

There isn't any answer checking yet, so currently the game will be
stuck in the first level, (even though the content for the other
levels _is_ available in the server).
