vs9/allinone.sln: Build GTK+-2.24.x

Have the all-in-one solution file build all of the GTK+-2.24.x build-time
stack.  Note that for full functionality, we still need to include libcroco
and librsvg, together with copying/installing the adwaita-icon-theme
package, so that the needed icons can be installed and displayed.
