Slothoth's Warfare Tweaks

There were some things that were bugging me about combat in Civ VII. Here are some tweaks I have done to either fix things to match descriptions, or to improve the feel of warfare, or to rebalance things, like how Infantry are not worth it a lot of the time. Amends the Commander mobility promotion so it actually ignore terrain restrictions, including Minor rivers, and rough terrain. It also works without having a unit packed. Amends the mechanic on losing influence per settlement conquered. Instead of receiving negative influence on your capital, you instead get that negative influence on the conquered settlement. This is both more readable and allows for "ransoming" cities in peace deals, without a permanent influence penalty. Grants a Sword of Brennus like effect to all civs. When you return a settlement in a peace deal, gain 100 gold, scaled by age. In that way, stupid forward settles by the AI can be a lucrative opportunity, instead of a pain in the rear. Infantry now get +3 strength on defense when on fortification. This was to make Infantry have a purpose and not be outclassed by Cavalry. WISHLIST: These are things I would like to do, but can't find a way: - Allow Army commanders (land) to get experience from naval unit combat in antiquity. It just feels so bad doing combat without getting that sweep experience. - Settlements in unrest from being conquered don't contribute to settlement limit. Two blockers for this, one, there does not seem to be a requirement that fits
