* glib/MissingIntPtrCtorException.cs : new exception to throw if unable to access an IntPtr ctor on a GLib.Object subclass. We need an IntPtr ctor to be able to wrap arbitrary object handles. * glib/Object.cs : have NativeType call LookupGType. * glib/ObjectManager.cs : throw the new exception in a try/catch. svn path=/trunk/gtk-sharp/; revision=27563
