Spawn Weight Multipliers

Using this fossil multiplies the spawn weights of all modifiers with elemental tags by 0, "physical and ailment" tags by 10, and "chaos and ailment" tags by 10.

All mod with cold/fire/lightning tags also have elemental tags, thus Corroded Fossil affects those mods as well.
