vs9/allinone.sln: Build Pango

This adds the Pango build into the build process for the all-in-one
solution file used to build the GTK+ stack.  Please note that at this time
the PangoFT2 DLL is not built in the process, as this solution file set
does not build FontConfig, which is required PangoFT2.
