This allows crushed ore to be meltable in a vanilla friendly way, which respects metal dilution(the ammount of crushed metal generated is based on the metal bits in the ore clump). 
Due to limitations in Json modding, crushed ore gives a 11% increase in bits. Pulverizing metals requires appropriately hard pulverizer caps. 

Due to limitations in .json modding, stack size of crushed materials is now 32(sorry, had to do to keep crucible safe).

I have added crushing/melting recipes to some metals that cannot be melted, in case other mods allow those materials to be melted some other way(crucibles cant go up past ~1300 degrees). 

This should work with new VS updates, and doesn't change any crafting grid recipes, only allows crushed metals to go in crucible and allows some ores to be pulverized that couldnt before.
