Fixed bug where bosses would sometimes drop items before the fight was over
(Uses MC_PRE_SPAWN_CLEAN_AWARD instead of MC_POST_NPC_DEATH)

No longer overrides Mirror World treasure room

TheresOptionsPickup / OptionsPickupIndex is only assigned to items in Boss Rooms and Treasure Rooms

CHANGES 5/17/21:
- Repentance support
- Rewrote the thing so it properly uses the API to handle item choices
- Should no longer despawn item pedestals when touching an unrelated collectible
- More options spawn in boss rooms now
- Fixed a weird crash where picking up a collectible would cause a segmentation fault

- NOT YET THOROUGHLY TESTED: preventing the mod from overriding important items/drops, like the polaroid etc. Should work with imporant Repentance items too
- Removed: spawning extra goodies for having More Options / There's Options; plan on changing item behaviors soon
