Gh pages korean

# Korean translation of choosealicense.com 

Hello.
I think the contents of 'choosealicense.com' are very simple and easy.
It is wonderful!
So, I translated choosealicense.com in Korean.
I made a new branch "gh-pages-korean" for Korean translation.
I've finished translation.

I hope choosalicense.com support Korean.

Please review my work and give me some information how to merge master branch or your plan about support multi-lingual.

Thanks.
