[GRASSLIST:1060] v.digit: Korean char input

Hi Korean GRASS users (or maybe Asian? i'm not sure :-),

Now v.digit's label commands support for input korean characters.
You can input korean characters by #define ASIAN_CHARS in
grass/src/mapdev/v.digit/dig_curses.c file.

You can not see any korean characters during input due to waddch()'s lack of
features. However, this doesn't matter for further uses. Korean characters
should be contained in dig_cats file.

Happy GRASSing!

Suggestions are welcome. <hdcho@geni.knu.ac.kr>
