added extra check for missing variables

-fixed typo in the save data loading function that could sometimes cause issues if specific conditions were met
-fixed red hearts being taken before soul hearts (code was checking if you had the crow heart trinket and some genius dev updated the GetTrinketIdByName function so it no longer works for vanilla trinkets)

- fixed mod killing keeper if the limit is set to half a heart
- fixed mod saving int values as floats in rare cases (stuffing up the save file)
- fixed mod sometimes trying to save data every frame when limit is set to less than 12 (potentially overwriting updated data)

config menu update

small bugfix

-fixed dumb repentance check

-fixed pack2 version not recognising multi heart items (like raw liver and PJs)
-fixed eternal hearts not being removed on damage without soul hearts if eternal was in extra health
-fixed tainted bethany and tainted judas having health getting messed up with bone hearts

fixed bug where player 1 would lose extra health when co-op players took damage
