* generator/Signal.cs : rmv Handle param to SignalCallback ctor calls. s/GtkSharp.Signal*/GLib.Signal*. * generator/SignalHandler.cs : rmv Handle param to ctors as it's redundant. s/GtkSharp.Signal*/GLib.Signal*. Use new Connect/Disconnect instead of generating DllImports into libgobject directly. * glib/SignalArgs.cs : move the the GLib namespace. * glib/SignalCallback.cs : expose Connect and Disconnect methods to hide some pinvokes that were previously generated. Also move to the GLib namespace. gnome/*Handler.cs : update to new SignalHandler API. gnome/CanvasProxy.cs : ditto gnome/void*Signal.cs : ditto svn path=/trunk/gtk-sharp/; revision=26778
