Add option to get pulverized metals from ingots

[andrewminer]

PROBLEM

Many players set up automated ore processing such that they wind up with only ingots available in their inventories. This makes recipes which suggest getting pulverized metals from raw ores cumbersome for them to work with as they need to do some translating in their head.

SOLUTION

Offer the calculation option to prefer recipes where pulverized metals are created from ingots rather than ores.

Likewise an ingot/block pair (e.g. diamond, gold, etc) can easily be constructed/destructed, but breaking down the block doesn't seem to be an option.
