huge smelting fix, read extended notes.

AL Kharid furnace rotated and placed against wall so that its usable.

Coal required for bars that need it.

Iron now has 50% fail rate as it should, even when making multiples.

Make X function now makes equivalent to a full load of ores. ex) make
all iron bars searches for 28 iron ore and returns 28 bars. Rune make X
looks for a full inventory of ores(3 bars worth) and makes that. If you
have less than a full inventory, you'll have to make one at a time or
use the make 5/10 if possible.

Hammer required now for anvil but it doesnt say it until the interface
is open (idk where to put the requirement check to fix this)
