[Derived from a patch by Ben Maurer] * generator/Ctor.cs : generate code to detect subclassing and handle GType registration and native object creation properly. * generator/Parameters.cs : add PropertyName accessor for param attr. * generator/Property.cs : use a new GLib.Value ctor. * glib/ObjectManager.cs : redo hash access. * glib/Object.cs : CreateNativeObject method to invoke g_object_newv and some refactoring of RegisterGType and LookupGType. * glib/Value.cs : make gtype field an IntPtr. * glib/glue/object.c : glue for g_object_newv use. * glib/glue/value.c : new glue for value creation. * gtk/Dialog.custom : fix a ctor declaration for auto-reg. * gtk/Gtk.metadata : mark a couple property_name attrs as examples. * sample/Subclass.cs : use auto-GType-registration now. svn path=/trunk/gtk-sharp/; revision=26916
