• Use object references instead of dict lookups
• Refactor the game configs to better fit object references

Bug Fix

• Fix a bug where fire emblem 7 item overrides did not apply

Add Cath Override

Cath's default behavior is to loot until she can't loot anymore and then immediately leave the map. If she randomizes into a class that cannot use lock picks, then she will just leave on the first turn that she moves. Instead, replace the lock pick with a chest key and give her a door key. So she'll at least do something before leaving.
