Sort Tech and Civic Unlocks
Makes it so that unlocked units and policy cards are sorted in tech and civic tree view. Useful if you have a bunch of new units or policy cards or mods that changed the types of vanilla policy cards and they are in a messy order which annoys you.
Units are sorted first by category (land -> naval -> air -> support -> civilian), then by cost.
Policy cards are sorted by slot (military -> economy -> diplomacy -> great people -> wildcard > other mod policy categories).
