Makes the font larger on the label that displays the card value.
Creates validation for the add value textfield - the card value must be between 1 and 999.
ISSUE: need to access errorField (in createDeckPanel) to display validation error when appropriate.
Also changes the size of the cards panel to better fit maximum number of cards even on a minimum window size.
