Add Korean (ko) translations.

These are somehow the old strings from before the UIs were revised. It
seems the automated Transifex updater scripts didn't create a new PO
file for Korean… that or I did something wrong. Either way, we can still
use *some* of these strings, so we should add them.

 * THANKS to ilbe123, cwt96, Dr.what, and pCsOrI.
