Gives all classes access to all of the class exclusive recipes that are locked behind traits. This, fits well with single player games.

Does not effect positive or negative traits of each class.

Jack Of All Traits is not exclusivly needed as it does the same thing as the command /worldConfig classExclusiveRecipes [true|false]. This is for those who don't want to mess with the serverconfig file or who, like myself, keep forgetting to make the config change each time a new world is generated.
