Add the Firefly font patchset. This patchset is mainly used to make
CJK TrueType fonts look prettier. Various enhancements like bold, italic,
readability, and embedded bitmap font help a CJK X desktop a great deal.
To enable this patchset, define WITH_CJK while building these ports (pango,
fontconfig, libXft, and freetype2).
