Move it to new harfbuzz-gobject library. Implement enums and boxed types for object-types. Still have to do boxed types for value types.
Makes documentation / introspection easier.
Initial setup of gtk-doc. Straight forward setup following the gtk-doc instructions. Ignore some troublesome types in src/hb-gobject.h. To build use "./autogen.sh --enable-gtk-doc" then "make". Docs are in harfbuzz/docs/reference/html/index.html.
