Add a utility project to get config.h and gdkconfig.h from their *.h.win32
(or win32_broadway, if applicable) counterparts, using custom build rules,
so that these "generated" files can also be removed on clean and
"regenerated" upon update. This also enables the removal of configs in
certain projects that isn't really needed as a result.
Also update and merge the projects and property sheets to include a single
property sheet that it needs, which will then in turn include the other
property sheets that is needed, so that things are cleaner.
Updates to the Visual Studio 2010 projects will follow later.
...for all files except the README.txt and the .sln files, which have to
have DOS/Windows line endings. This makes application of patches, when
applicable, easier.
We need to copy the GDK .lib/.dll from Release_Broadway\<Platform>\bin
or Debug_Broadway\<Platform>\bin to Release\<Platform>\bin or
Debug\<Platform>\bin respectively during the build of Broadway flavors of
GDK, as the MSVC introspection builds expects the GDK .lib/.dll to be
in Release\<Platform>\bin or Debug\<Platform>\bin.
Use a new property sheet to do so for Broadway builds of GDK-during the
builds of Win32-only GDK, the broadway builds of the GDK .lib/.dll would
be cleared out prior to the build of the Win32-only GDK.
