DungeonGen refinements
--More Big Key door considerations
--Backtracks earlier when hook candidates comes up empty
Minor work on key shuffling - lots of bad rules still
Playthrough gen doesn't flood swamp keys now
Crystaroller Stairs fixed
More Full ER support
Added DungeonGen check for hangers without enough hooks
DungeonGen doesn't consider BK door problems unless starting from origin
--This could cause some longer gen times - as the origin is hooked up last
Skull 3 Exit - attempt to fix
Fixed key door candidate finder to stay within own dungeon
Standard mode support added
Added missed Pre-moldorm chest
Started work on new key logic analyzer
Fixed clock -> process_time for Python 3.8
Fixed interior blocked doors
Vanilla logical connections for Ice Cross (Push block)
Dungeon entrance enhancement for TR, Skull, HC (Standard)
Kill on invalid dungeons during key door shuffle
Key logic improvements (Smallkey restrictions, Logic Min/Logic Max for key doors, Big Chest doesn't count for small keys if BK not found yet)
Key door candidate now accounts for "overworld" dungeon traversal
Path checking added some Crystal Logic (Blind's Cell to Boss mostly)
Kill on dungeon gen if taking too long
