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.
(probably) fixed glitched pyramid spawn issue
fixed sanctuary purple chest spawn
added switch to allow tablets to be opened with hammer (graphics not ready but looks ok)
