Alternative way of handling copper and iron and crafting steel.
Mod adds special electric melting furnace and molten form of copper, iron, steel. One copper/iron ore going through the process should result in 2 plates (plates are crafted in standard assembler mk2).
Steel is made by melting 5 iron plates to molten steel and crafting it in assembler mk2 (results in 2 steel plates).
As a bonus mod gives you molten form of plastic and sulfur for alternative storage/transport.

Mod uses vanilla electric furnace graphic for the smelter atm.
It shouldn't cause any incompatibilities. NOT tested in MP.
Any suggestions welcome. Have fun!
