New slight AI improvement.

New improvement to the aggressive and active aspect of the AI

-Fixed the bug known in the game since its release: the AI ​​which allows itself to die of attrition during a siege, now there is a 50% chance that the AI ​​forces an attack exit, even if it does not does not have enough strength (does not interfere with the AI's strength judgment)
