2023-07-01	Add "snapshot" replay view during play.	Tor Andersson
	Snapshots store game state without undo and only log length. Combined with the final game state's log we can recreate the view from any snapshot quickly. Move replay code into separate script file, loaded only when used. Prefix system "setup", "resign", and "restore" actions with a period.
