[ft-devel] more Unicode character blocks for CJK autofitting

[Werner LEMBERG]

I've just updated the ranges for the CJK autofitter as below.  In
particular, I've added Hangul Korean syllables which have been missing
(I no longer can remember whether this was intentional).  Please
comment.

If there aren't objections, I'll release a new FreeType version within
a week (hopefully, Toshiya-san finds time to review his configuration
patch).
