Reclaim items automatically when you respawn instead of needing to run back to corpse
"Rewrite" reclaim manager so it only has a single reclaim per player
- timer refreshed every time you die but it should give out every item when you respawn anyways
- also remove storage of killer name since that was used for reclaim backpack naming
Remove reclaim backpack code & prefab since it's not used anymore
Reclaims still expire after 2 hours (convar)
Put items back into respective inventories (main, wear, hotbar, backpack)
- put backpack contents into main inventory if you don't respawn with a backpack due to reclaim
Add new inventories to protobuf & run codegen
