Add a better ordering to languages.

This is kind of arbitrary, but here's my reasoning:

- Japanese goes first, because it's the original language.
- ja-kanji and roomaji follow because obviously we don't want to split
  Japanese up.
- Korean and Chinese go next to keep Asian languages together.
- Then English, because it's the main language other than Japanese.
- Then French and German, because they translate their Pokémon names???
  idk it feels intuitive to me.  Plus I guess their IDs are next.
- Then Spanish and Italian, because they're the only official languages
  left.
- Czech goes last because it's unofficial.
