Added difficulty config option vanillaSmelting. False by default.
Makes smeltery ingot return 1 for each ore.
Alloy output adjusted for equality to non modified version.
Added "smeltery output modification" config section.
Adds ability to customize ingot output of ores thrown into the smeltery and also the output of ingots when alloys are made.
Removed ingotsPerOreNetherOreMod variable.
Since Nether Ores from the Nether Ores Mod always give 2x normal amount, config option was removed.
Fixed ingotsBronzeAlloy default value.
