Add in functionality for splitting your hand when you have a pair of equal value cards.

[jstaahl]

If the user has two cards in their hand of the same value, an extra option to split their hand should appear on screen alongside "hit" and "stay". Add in the proper game flow to play each hand individually.

Also remember a hand can be split more than once. (User is dealt two 6's, they split... When playing their first hand they are dealt another 6, they split again....)

Started but not completed. Currently if a player has 2 cards of equal value a "split hand" button appears. This will split their hand, deal a new card to each new hand, and display both hands and their values. However, the code to actually be able to play both of these hands after creating them has not been implemented.
