Resolved issues #92,#104. Other minor fixes.

Added "minbet", "shufflepoint", "maxplayers" initialization options for Blackjack. Updated display of PokerHands with the rest of the hand that wasn't included before (aka. not the 5 best). Updated "test1" for Texas Hold'em Poker to take a parameter between 2-5 to simulate 2-5 players. Updated "grules" strings to reflect changes.
