Adding third_party/ibus-hangul/ to the Chromium OS build.

ibus-hangul provides an input method for Korean.

- third_party/ibus-hangul/libhangul_0.0.10-1.diff.gz
- third_party/ibus-hangul/libhangul_0.0.10.orig.tar.gz

These files are source package of libhangul for Ubuntu Lucid (10.04 LTS) at http://packages.ubuntu.com/en/lucid/libhangul0-data.
Since Karmic's libhangle (0.0.9) is too old to build ibus-hangul trunk, we'll build libhangul packages ourselves.

- third_party/ibus-hangul/make_pkg.sh

This script first builds and installs libhangul debian packages, then builds ibus-hangul.

- third_party/ibus-hangul/ibus-hangul_1.2.0.20090617-2.diff.gz

Copied from the Ubuntu Karmic's ibus-m17n package just like as third_party/clutter/clutter-1.0_1.0.4-0ubuntu1.diff.gz.

- third_party/ibus-hangul/ibus-hangul_remove_python_deps.diff

Patch for third_party/ibus-hangul/debian/rules which removes setup tools written in Python from the ibus-hangul debian package.
