Chest Minecard

Since the new raw-metals are introduced, you get raw metal from the ores. Mine-shafts were there to collect goodies, like e.g. Iron. But even though the raw Metals are now added, the content of the chests still are Iron Ingots. The raw metal in a mine normally isn't already smelted, so it would make more sense to put raw metals in the chests, that ingots.
