Finally done with translation

[Nubi KR]

It took me two days to translate the whole thing.
There were some translations before, but lots of awkward translations, so I had to translate all again.

Most of the translations were not difficult, but the difficult part for me was the server-related settings.
I'm lacking server related knowledge, so I had to learn about them to translate. XD

For the advanced settings, I can't say that they are perfect because I haven't used NodeBB for a long time, but I can confidently say that they are perfect for the functions I used myself.

It was a good experience to localize NodeBB.
I will continue to improve translation.
