- make two-player handshake work
- make Danny happy because now we can have better screenshots

The following 3 issues will have to be solved to complete the work:
- use client-side chip-flipping or propagate it from the server
- game over not handled in the GUI yet
- disallow "new game" or modify it to trigger the play-again feature
