	* app/widgets/gimpdockable.[ch] (gimp_dockable_detach): new
	function.  Need to include ugly stuff for proper GimpImageDock
	setup.

	* app/widgets/gimpdockbook.c (gimp_dockbook_menu_end): use
	gimp_dockable_detach() and removed the evil includes.

	* app/gui/dialogs-commands.c (dialogs_detach_tab_cmd_callback):
	implement it using gimp_dockable_detach().
