Bug 636190: Visual C++ 2008 Project Files

These are the Visual C++ 2008 Project Files for building ATK, along with
a hand-written config.h.win32(.in) that is used for the purpose.  This
attempts to create the project files in a way that is similar to what is
being now done in GLib and GTK+

*The configure.ac and Makefile.am files are updated so that a config.h.win32
 can be expanded with the updated version info with each tarball release.

*The atk/Makefile.am file is updated to re-enable the distribution of the
 expanded atk/atk.rc file and also to enable the creation of
 build/win32/vs9/atk.vcproj from build/win32/vs9/atk.vcprojin with the
 correct source file entries in the project file with each tarball release.
