* generator/Signal.cs : add try/catch blocks to native callback delegates so that exceptions are not propagated across the native boundary. Now raises GLib.ExceptionManager.UnhandledException. * glib/ExceptionManager.cs : new class with UnhandledException event and a static method to raise it. * glib/Signal.cs : wrap the generic EventHandler callback delegate with try/catch blocks and raise the UnhandledException event. svn path=/trunk/gtk-sharp/; revision=73840
