* generator/Parser.cs: use XmlDocument.Load (Stream). The one using (String) expects an uri. * generator/Signal.cs: always remove the delegate from the signal callback (prior to this, the last handler was not being removed). Dispose the callback (ie, disconnect from the signal) when there are no registered delegates to handle it. * generator/SignalHandler.cs: added 2 new fields to hold the instance and the handler ID. The finalization is now done in Dispose and disconnects the signal handler when no delegate will handle the signal. Changed gobject-2.0 to libgobject-2.0-0.dll. * glib/SignalCallback.cs: implemented IDisposable interface. svn path=/trunk/gtk-sharp/; revision=11976
