[Tutor] Blackjack Betting

[Vincent Balmori]

I was able to get the program started without errors now. What is left now is
to: 

Having the stash change after winning and losing. No matter what, the value
in stash stays the same. The conditional statement I made which prevents
players with no money from playing is dependent on this.

After each game when I choose to play again, the betting options do not come
up again before the cards are drawn.

Apply the betting option to more than one player the same way each player
can choose to hit. I think the key involves modifying the init function in
class BJ_Game, where it adds the number of players and names.
