added TODOs from feedback.
updates needed after adding GameResponse returns from game engine.
everyone now gets hands shown at start of turn in a notice. current player gets told it is their turn in a notice when it is. Added GameResponse class which allows teh game engine to talk to all players for any command. fixed bug that had hanabot ignoring private messages.
added new GameResponse class. encapsulates return value, and list of string responses to the channel, and each player in the game.
added *.un~ to ignore file. apparently that's what vim uses as tmp files on Mac OS
