* src/glade-widget.c: Fixed bug in glade_widget_dup_internal ()
	  (stupid typo of mine when fixing 320077)

	* src/glade-utils.[ch]: Removed all the Cut/Copy/Paste/Delete
	  stuff, now all in GladeApp.

	* src/glade-app.c: Moved the bulk of code from glade-utils to
	  glade-app (cut/copy/paste/delete) since it was confusing to
	  see the chain of events, it should be simpler overall now.

	* doc/glade-sections.txt, doc/tmpl/*: Adjusted doc structure
	  for new apis and removed old apis.
