Artifacts Ammunition (and possibly other) keyword translation

Summary I would really love to be able to rename Ammunition 1/1 to the Polish equivalent. Could also use with other keywords, such as Durability.

Usage It would enable soo much more localization and utility for users.

Value It allows people to use the plugin on non-english servers to the fullest.

Priority

Utmost priority, since more people would be able to translate their items.

Implementation Change the keyword "Ammunition" in the plugin to a String given by a user in a config file.
