Improved and more impactful change to make auto resolve more logical and visible

-Correction of the bonus granted to the player on settlement bonuses (on vanilla it was too high)
-Slight reduction of the bonuses granted by level of the general (this will avoid having an army of 20 units against 1 hero lvl 50 and where we are losing)
-Correction of the bonus granted by campaign level for global auto resolve, this time it is more legitimate
-Balancing of various bonuses higher for the player than for the AI, they are now legal
