Implement drawing a card off the deck

* Move deck container handling into the Deck itself

* Create a player object

* Add a button for the player to draw a card
Functional draw card interface and js refactor

* Blackjack.js split into deck.js and card.js

* Player deck and table deck are both just different decks

* Table deck explicitly initialized in index.html.  May need to refactor
  in future.
