Shifted version to 28

1.  Shifted version of Chromium to 28 as version 27 is still supported upstream.

2.  Modified the script to add -y to the yum so no manual interaction is required.

3.  Added the patches to come before running configure (needed for sure for c21c51a patch as that must be in before running build/gyp_chromium ... decided to patch everything first as RPM normally does)

4. Modified the spec file in chromium_rpm_packager.sh to change owner to root and modified the license as some parts are LGPLv2+ (parts of ffmpeg).

5.  Added ARCH detection and glibc.i686 and libstdc++.i686 for building on x86_64.

6.  Got permission from NuxRo to use his packages.

7.  Modified the obsolete_info_bar patch to be disable_os_info_bar_el6.patch as they changed the text and the label to not say obsolete.

8.  Added BUILDROOT to the rpmbuild directory via chromium_rpm_packager.sh and not the spec file.

9.  Added --define 'debug_package %{nil}' to the rpm binary build line so that rpmbuild does not try to strip out debug info.

10.  Modified the readme.txt to point to the new CentOS location where the RPMs are stored.  This will eventually make it into the CentOS 6 extras repo.
