API for facilitating custom item tiers drop tables

[xiaoxiao921]

BasicPickupDropTable, the system looks kinda nightmareish for us (very good unity editor workflow but horrible extensibility)
Not even sure on a clean solution for this / if this will be ever tackled

my understanding is that for people wanting to add their simple custom items with custom tiers to chest is that they have to load each individual chest prefabs and modify the drop tables accordingly, if they can't through that because of the run regeneration drop table timing they have to hook the method and do a match on the name or similar
