Fix deal order

[bumper314]

I see in BlackjackGame.cpp that you deal the dealer first, then the players. Also, each person receives two cards each time rather than going in true deal order. I doubt this affects the probability, but fixing the order gives me a little more confidence in the results.

Here's a patch file:
