In vanilla, gamerules are global, across all worlds. Maps created for vanilla that use command blocks expect this behavior, which is broken when they are placed on a world that is not the default world (world #0). This commit changes that by using the command block's current world when executing the command, forcing the game rules executed to be executed in the world the command block is currently in.
