Introduction of challenging by agents

The AI agents are now able to challenge each other's actions or counter actions. This makes for a much more interesting game!

Bug-fix: Force Coup

If the agent has more than 10 coins, they have to perform a coup. Any other action is invalid.
This makes the game actually come to a close instead of the agents just gathering coin.

Minimal working version

The AI agents can play a game where they can only perform actions. No challenges or counter-actions. They play until completion and then the game ends. They throw some wit and challenges in between. Its fun to watch them play!
