Added action logging during attack/block of the AI player. To do that, I wrapped some of the direct access from the player to the action layer into the game observer.

First version where I managed to finish a normal game while undoing several actions until the end. There are still some problems in direct damage spells and interruption management. I added several assert in the code to catch them.
