Better batching support for mass testing of seed generation.
Generation issues fixed:
--Filler now tests with the key in the proposed location to enable alternate key rules
--Key rule checker now only considers key locations that the parent sphere did not have - better key rules
Added rule for Freezor chest (for crossed and swordless)
Added more "single exit" caves to possible inaccessible regions
Prevented dungeon gen from assuming you could get GT Big Key at Aga 2
Prevented cross-dungeon contamination during key rule gen
Fixed some key-sphere merging problems (I'm ready to get rid of spheres now)
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
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
