* 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
