Add a new rom flag to disable fake Light/Dark worlds from occurring as a result of underworld travel. (Other methods of fake worlds like YBA Fake Flute are not changed). Entrance Randomizer intends to use this flag to fix the Fake Light world from traveling though sewers when Hyrule Castle is in the dark world, as well as to implement new shuffle modes that involve deliberate cross-world caves without needing to grant pearl and mirror like the current insanity mode does.
