Status Window now updates the number of cards in play when an opponent gets a bingo.
Fixed an off-by-one error with currentBingoNumber. Changed bulky if-else statements to switch/case for readability.
Computer response times are implemented. Integer queue added as buffer, allowing up to 6 seconds of delay. I'm hesitant to go any longer, because the delay gets ridiculous towards the end. If we want, we can set a fixed size for the queue so that if slow opponents get TOO far behind, they'll start missing numbers. Joshua: the delay causes a couple of bingos to get called even after a round is over. I'm not sure if we need to worry about this, or if it's fine...
