Repair Custom GreatWorks

Mod Ability 1. Repair custom great work slots can not work. 2. Support customize theming text to any building（instead of XX (building) has determined the theme, culture and tourism). performance increased by 100%）. 3. Support for similar theming in custom slots（Not perfect）. 4. Fixed the issue where only numbers could be used for the suffixes of relics and artifacts. 5. Fixed the issue that the modifier on GreatWorks need to be moved once to work. 6. Supports adding additional text to any GreatWork. Modder Guild 1. The mod does not support to adding or reducing slots dynamically(For example,attaching the Modifier to policy card). Because the game does not support it. If you use a Modifier to add slots,when it takes effect,the great works that already exist in building will disappear,when it lapses,it won't change at all. 2. Do not use "Building_GreatWorks" to add custom slots,as it will not take effect. You can attach the modifier in "TraitModifiers" or "BuildingModifiers". If you use "TraitModifiers",the "SubjectRequirementSets"or"OwnerRequirementSets" must be null. If you use the other you can only use the "SubjectRequirementSets",and the RequirementType must use "REQUIREMENT_PLAYER_LEADER_TYPE_MATCHES" or "REQUIREMENT_PLAYER_TYPE_MATCHES",or not using RequirementSet. 3. The mod does not support attach modifier via lua. 4. The ModifierType must use "MODIFIER_PLAYER_CITIES_ADJUST_EXTRA_GREAT_WORK_SLOTS". 5. If you need theming,use "RGW_Theming" please(refer to readme in the file for detail)，It is not perfect for yield, keep yields of great works in the building are not repetitive please. For example, if you have three custom slots in Palace,and it is full, yield of the first great works is culture,the second is faith and the third is gold,this is more normal,if their yields are culture,it will be confusion in yield. If you don't mind this, help yourself. The 'ThemingYieldMultiplier' and 'ThemingTourismMultiplier' can only be a multiple of 25 within the range of 100 to 3000, includi
