Add program translation

jp/en/zh -- only english has been translated (duh)
keep in mind this translates the text in the program, not the internal flag names.

not sure if other languages need to be supported; from PKHeX's experience, only spanish is updated (besides jp/zh), as most users speak english or are fine using the program in english.

pls localize villager names and item names for non-english :P -- preferrably automated from raw game dumps
