Unlockable Opponents

Added a new View, where you can choose which opponent to battle. To unlock the next opponent, you have to defeat the current one. They play with stronger cards the further you get, but you can also gain stronger cards the further you get.

The AI is now a little bit better. Instead of placing the first card on its hand on the first free slot, it places a random card in a random free slot. Coming up with a decent AI is much harder than I initially thought and so I moved that point to the end of this project.

I also added a "How to Play" Area where all the aspects of the game are described and I added a few new cards like "Boneweed" and the "Snowbunny".

You can also lose the entire game now, if you lose so many cards that you only have 4 and can't build a new deck, because a deck consists of 5 cards.
