Split the property sheet into four sheets, to make maintainance of the
build files easier, and also to prepare for using autotools to fill in
the parts for the "installation" of headers.
Also put more of the items that are repeated in the projects into the
property sheets, also to improve ease of maintenance.
Updates to the Visual Studio 2010 projects will come later, as the script
to update them to Visual Studio 2012 must also be taken into account during'
the process.
Add projects to build the glib-compile-resources and gresource(-tool)
utilities, and "install" these tools upon successful compilation, and dist
the new projects.
One piece of note: will it be better to dist gconstructor_as_data.h instead
of generating it in the VS build process (I generated it in the property
sheet update in this commit)?
Visual C++ 2010 projects will follow shortly.
