        * Mono.Windows.Serialization/ObjectWriter.cs: code to build objects at
        runtime from a xaml file. Current problems are with events and
        delegates (current behaviour is untested and possibly useless) and
        DependencyProperties (not implemented yet)
        * demo/runtimetest.xaml
          demo/runtimetest.cs,
          demo/Makefile: creation of objects at runtime from a xaml file
