GT filler and smith locations fixes

GT now pre-fills with junk if it's in the vanilla location regardless of the state of the shuffleganon flag.

The smith is now allowed to be in multi-entrance cave locations in the appropriate shuffles. A duplicate Old Man Cave (West) from bomb shop multis was also removed.
