Update mod order logic [beta]

[RedContritio]

For mods not contained in rules, if their categories is not empty, try to find out it's order based on mapping from categories to rule name.

Specified categories is shown as following:

        public static readonly Dictionary<string, string> category2ruleType = new Dictionary<string, string>{
            {"GUI", "Ui"},
            {"Graphical", "Graphics"},
            {"Races", "RaceEdits"},
            {"Factions", "FactionEdits"},
            {"Buildings", "Buildings"},
            {"Clothing/Armour", "Armor/Weapons"},
            {"Items/Weapons", "Armor/Weapons"},
            {"Gameplay", "Overhauls & Big additions/world changes"},
        };
