-Added projects to compile the a11y portion of GTK+. This is now necessary
as a11y/GAIL is now integrated into the main GTK+ library, and it must
be built before compiling/linking GTK+. This project is done like the
GDK/GTK+ projects, where the source file listings for the VS2008/2010
projects are fed into templates (.vcprojin, .vcxprojin and
.vcxproj.filtersin) during 'make dist'
-Added projects to compile the libgail-util DLL (no templates for this
as this does not have source files added/removed often)
-Added the new projects into distribution, and headers, DLLs and .LIB files
into the "install" stage
-Reinstate build/win32/vs10/gtk+.sln with the correct EOL (DOS/Windows), so
that it will be correctly recognized by Windows instead of having the
annoying "Unrecognized Visual Studio Version".
-Update property sheets to reflect on new headers added
-Change the demo program to be gtk3-demo.exe, to be consistent with the
names on other platforms, and updated/renamed related project/solution
files, and added overlay.c to the list of demo sources.
