commit 99d79453da0630cf2eb205658bdeef0131b1026f

    tests/glibmm_interface_implementation: Use the new base class order
    
    * tests/glibmm_interface_implementation/main.cc: Interface before
    Glib::Object in the list of base classes. Test a custom property and
    an interface with properties.
    This patch is almost identical to the attachment in bug 697229 comment 14.
