* glib/UnwrappedObject.cs: New class which holds an IntPtr. This is used in Value so that we can retrieve the IntPtr itself for an object property. * glib/Value.cs: Add UnwrappedObject cast operator. * glib/Property.cs: If the retrieved value is an object, and there is no wrapper object, create a new one. svn path=/trunk/gtk-sharp/; revision=5440
