Bug 643270: VS2010 Project Files (autotools)

-Update to distribute the VS2010 files.
-Added rules in Makefile.am's of GDK and GTK to fill in the
 project/filter files templates with up-to-date source file
 listings to simplify maintenace.

Any comments on the usage of the VS2010 files are welcome!
