Incorrect Elfdalian translation for newer items

In Elfdalian newer item names are just taken directly from Swedish. this results in a lot of parity mistakes like axe usually being called ökse but for the copper axe its called yxa. similarly all the material name also mismatches for all the spears compared to all the older items. Aditionally the name for copper changing from kupper on the copper block to koppar on the tools.
