Made menu options case-insensitive as I am too lazy to hit shift.
Pulls the game info immediately upon joining a game, so the user can see
it.
Time-stamped most of the non-menu printlns.
Fixed a bug in the UI where if you made a bet, then left the game
session, then came back into the game session, the UI (not the server,
it was right) incorrectly thought that you had a bet placed. It wasn't
'cleaning up' the UI properly when moving between screens.
