Korean translation update for 2.2-stable
This korean translation patch is and also for r10998 (current trunk).
I wish this patch could be applied into the redmine 2.2.0 version, which is going to be released soon.
The update consists of refining some awkward translations and introducing new translations:
- fix awkward translation for 'commit', 'tag', and 'branch' :
제출커밋, 표지태그, 분기브랜치
- fix translation for 'duplicates' and 'duplicated by' : 다음 일감에 중복됨, 중복된 일감
- fix translation for 'issue watchers' to '일감지킴이'
- some new translations on fields, workflow and archiving projects
- other minor & trivial fixes
