* HACKING: Change format to make popt "pop" out more.

	* libnautilus-extensions/nautilus-entry.h:
	* src/file-manager/fm-properties-window.c: (create_basic_page):
	* src/nautilus-bookmarks-window.c: (on_text_field_focus_in_event),
	(on_window_delete_event):

	* libnautilus/nautilus-undo-manager.h:
	* src/ntl-window-private.h:
	* src/ntl-window.c: (nautilus_window_constructed),
	(nautilus_window_real_set_content_view),
	(nautilus_window_get_undo_manager):
	* src/ntl-window.h:
	Got rid of the undo manager parameter for the enable_undo
	operation.
	Eliminated code that sets up the undo manager except for the top
	widgets. We only need it attached to windows and to the top widget
	in each component.
	Change callers to get the undo manager in a few simple ways
	instead of calling gtk_object_get_data directly. Added some calls
	to attach the undo manager to an arbitrary object.

	* libnautilus/nautilus-undo.idl: Added comments to the IDL and
	also added the Undo::Context class.

	* libnautilus/nautilus-view-component.idl: Removed the dependency
	on the undo IDL and the undo_manager attribute.

	* src/nautilus-bookmarks-window.h:
	* src/nautilus-bookmarks-window.c: (create_bookmarks_window):
	Changed interface to take object to inherit the undo manager from
	instead of the undo manager itself. Got rid of unnecesary undo
	manager setting.
	(nautilus_bookmarks_window_save_geometry): Also changed interface
	to use GtkWindow instead of GtkWidget.
