add E_OBJECT_CLASS_ADD_SIGNALS and E_OBJECT_CLASS_TYPE to ease migration

2001-10-05  Michael Meeks  <michael@ximian.com>

	* gal/util/e-util.h: add E_OBJECT_CLASS_ADD_SIGNALS and
	E_OBJECT_CLASS_TYPE to ease migration to Gnome 2.0 from
	a single source base.

	* All C files:
	s/object_class->type,/E_OBJECT_CLASS_TYPE (object_class),/g;
	s/gtk_object_class_add_signals([^\(]*)\(([^,]*),([^,]*),([^\)]*)/
	E_OBJECT_CLASS_ADD_SIGNALS\1(\2,\3,\4/;
