New file and functions to handle undo in NautilusEntry and GtkEditables.

	* libnautilus-extensions/nautilus-undo-signal-handlers.c:
	* libnautilus-extensions/nautilus-undo-signal-handlers.h:
	(nautilus_entry_user_changed_callback),
	(nautilus_undo_setup_nautilus_entry_for_undo),
	(nautilus_undo_teardown_nautilus_entry_for_undo),
	(free_editable_undo_data), (free_editable_object_data),
	(editable_insert_text_callback), (editable_delete_text_callback),
	(editable_register_edit_undo),
	(nautilus_undo_setup_editable_for_undo),
	(nautilus_undo_teardown_editable_for_undo),
	(restore_editable_from_undo_snapshot_callback),
	(editable_key_press_event), (nautilus_undo_editable_set_undo_key):
	New file and functions to handle undo in NautilusEntry and
	GtkEditables.  This file is intended to contain signal handlers
	that enable undo for a variety of GTK widgets. Calling a
	setup_for_undo function will prepare the widget to handle
	undo functionality.

	* libnautilus-extensions/Makefile.am:
	Added entries for new files nautilus-undo-signal-handlers.c
	and nautilus-undo-signal-handlers.h

	* components/notes/nautilus-notes.c: (make_notes_view):
	Fixed bug #973.  Add undo to notes component.

	* components/websearch/ntl-web-search.c: (make_obj):
	Changed to use new undo signal handlers.

	* libnautilus-extensions/nautilus-entry.c:
	(nautilus_entry_initialize), (nautilus_entry_key_press),
	(nautilus_entry_set_text), (nautilus_entry_delete_text):
	Removed old undo code that had been rendered obsolete by the
	new signal handlers mentioned above.

	* src/nautilus-bookmarks-window.c: (create_bookmarks_window):
	Changed to use new undo signal handlers.
