TFMG Casting Fix

This mod changes the amounts of fluids needed for casting hard-coded into TFMG to match with the ones used by most mods.

Fluid amounts:

• Block Mold: 1296mb
• Ingot Mold: 144mb
• No mold: 16mb

The amount needed when no mold is inserted is the standard one for a nugget. This is currently not used in Vanilla TFMG, but may be useful for modpack authors.
