Add Visual C++ 2010 projects to compile GResource tools

Added projects to compile the glib-compile-resources and gresource(-tool)
utility programs during the Visual C++ 2010 build process, "install"
the resulting binaries upon successful compilation, and dist the new
.vcxproj and .vcxproj.filters files.

Also updated the property sheet and "install" project to make sure the new
.exe's are indeed "installed" and removed from the "install" project the
dependency on the testglib project as testglib is not an exhausive test on
GLib and people might want to make that project compile different test
programs as they might need.

Just wondering: I have updated the property sheet to create the
gconstructor_as_data.h header for glib-compile-resources, but is it better
to dist that generated header instead as the VS 2008/2010 projects will
depend on a working installation of PERL on Windows?
