	* app/Makefile.am: grouped the files together which will go to gui/.

	* app/widgets/gimpdialogfactory.[ch]: maintain a list of open
	GimpDocks for session management.

	* app/widgets/gimpdock.c: register open docks with the dialog
	factory.

	* app/widgets/gimpdockable.[ch]
	* app/widgets/gimpdockbook.c: pass a pointer to the GimpDockbook
	to the GimpDockable's "get_tab" function because the function is
	called before the dockable is added to the dockbook.

	* app/test_commands.c
	* app/gui/dialogs-constructors.[ch]
	* app/gui/dialogs.c: changed accordingly.
