Add: Corporeal Beast Drop Table Restoration

I'm bad at math and numbers so I did this again properly with the help of Crop's amazing tool, and I also decided to overhaul Corp's entire table because he deserves better. It was a mess.

This is the last time I do drop work.

Cave Horror:

• Corrected weight of Black mask (10) (~1/512)

Corporeal Beast
