Suggestion: support i18n

I think like classes,races,area name we can use like json control,or we can read from dbc.
And also item link we can modify in conf. maybe cool!

feel free to implement it. my only request would be to not use any wow files (no dbc reading). for the translations you can either use HOCON (so can be read with typesafe config), java.util.Properties, or simple csv would work as well.
