(acf0cb343) Fixes to EnableWorkShopItem: - Don't allow enabling if the item is not compatible with the user's version of Barotrauma or if it's a core package that's missing some required files. - Don't allow enabling if the item external files referenced in the content package are not found (e.g. if a mod uses vanilla files but the vanilla files aren't found).
