commit a8c1ba5a38b4570ae6d5788235ff55ae94221810

    Use libxfce4ui instead of support library.
    
    There are no exo applications that do not (or should not)
    depend on libxfce4ui. This somewhat forces them to port from gui4
    to 4ui.

-The exo-support library is an internal library used by the tools provided by
-the exo package. It currently contains two widgets copied from libxfcegui4
-to avoid readding the dependency on libxfcegui4 (we will later use libxfce4ui
-when its cleaned up, but that's unlikely to happen before Xfce 4.6).
