Additions;

    *Added the ability to purchase new random cards from the jail.

Fixes;

    *Fixed a bug where the player's hand would carry over between runs.

    *Fixed a bug where a card would stay in an 'active' state after playing if another of the same card was in your hand. Unfortunately, I didn't fix that it plays the other card--which doesn't change much since they're both the same card regardless.

    *Fixed a bug where discarding a hand after starting to use a card would have that card carry over into your next turn.
