Added PickANumber and small changes

Deleted some excess files, and added PickANumber.
Win/Lose

I updated Poker to determine what the Player has for a Hand (i.e. one
pair, two pair, straight, straight flush, etc.). Poker also sorts every
Player's Hand before determining what they have for a Hand (made my job
easier). BlackJack now changes the Dealer to NULL if they bust(). I
don't think I'll be touching these anytime soon now that I finished this
update. *Easier readability and bug fixes*
