New card, faster gameplay and some debugs

Quick update: 

1. There are new cards to be unlocked, with new powers.
2. The game is made faster, the AI thinks faster and card info is no longer shown during gameplay.
3. A random "stuck" message in the middle of a game is solved. (I made a stupid miscalculation)

I am always happy with feedback, so if you found something wrong about my game, please let me know.
