Prune language list

Rationale:
- Reduce translator confusion for when there are only two instances of a language in the list which appear identical by commenting out the entry with the region code
- Focus translator effort by only including one language entry from those languages that legitimately could have multiple entries. Spanish, German, and French fall into this, but I don't think the overhead of making sure the languages are maintained is worth the potential added localization.
- Only exception to the above is Chinese where the character sets differ.
