Molten Electrum Localization

Added localiztion for "fluid.electrum.molten", which I think it missed because it was confused with "fluid.platinum.molten" (it's the only localization for Molten Platinum, while electrum is the only missing) and i would deleat it if you give me the permision.
Also changed tile.metal.molten.electrum.name
