Remove "KKuTu Korea" and "KKuTuDotNet" and replace them with "KKuTu"

These two pages are showing Private Server that running web-game "KKuTu".

And they made a new page for their service.

So that two pages are for same game, but showing as different game.

So, I thought it should be merged into "KKuTu"

It's not illegal private server. You can find its source on github.

Pages:

KKuTu Korea (https://www.giantbomb.com/kkutu-korea/3030-70274/)

KKuTuDotNet (https://www.giantbomb.com/kkutudotnet/3030-79040/)

@nekop: Done.
