Korean translation file

First of all, thank you for the great tool. This is exactly what I want. I've been using it with great pleasure.

I attached korean language file here.

Can you please merge this file to this project for Koreans? I hope more Koreans will favor this program through this language file.

This may not be completely done but I translated it as possible as I can. It is much better than the automatically translated one though.

Thx!

Start by reviewing the attached ko.zip and locating how WindTerm stores and registers its language files. Compare the Korean file with existing localization files and verify that the application loads it correctly; done means the Korean translation is integrated without breaking other languages.
