Define ISOLATION_AWARE_ENABLED for the build of the GTK DLL so that visual
style can be applied to the Windows print dialog for all applications using

Update the script for the generation of gtk-win32.rc for MSVC to not try to

Broadway builds
-Decouple the Visual Studio property sheets, to simplify maintenance and
enhance flexibility for different builds
Visual Studio 2010 projects updates will follow later.
