Added colors!!

-Renamed Log to Display.
-Moved all Console references to Display class.
-Added color logic to Display class
-Fixed bug where Ace logic was incorrect
-Fixed bug where Dealer would still play even if player had busted

Notes: I still need to fix a few of the display tasks. I don't want to
too closely couple the console UI to any future UI that may come into
play, but the gameplay could stand to look a little better, even in the
console.
