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

Closes#47 by implementing things in a more abstract & extendable way. Thanks @jfmherokiller for the example implementation which served as an inspiration!
