/*
 * This implements the player (client) portion of blackjack.  It's
 * pretty stupid, basically a big case statement.  It listens to
 * the dealer (server), and updates the screen, getting input from
 * the player when necessary.  Here are the commands it sends and
 * receives:
 *
 * commands to client:
 *
 * Pnplayername		add player playername as player n
 * Mstring		display string as a message
 * Rstring		display string and get single char response
 * rstring		display string and get string response
 * Cnhstring		display string as cards for player n hand h
 *
 * commands to server:
 *
 * H			hit with another card
 * S			stand
 * T			split
 * D			double down
 * Q			quit
 * (plus plain old string)
