	Started to get rid of the gdisplays_foo() functions in
	app/display/gimpdisplay-foreach.[ch]. Work in progress...

	* app/core/gimp.[ch]: added the display list to the Gimp object
	(as a GimpList of GimpObjects). This way we get more independent
	from whether there is GUI or not, as gimp->displays will simply
	be an empty list for the --no-interface case.

	* app/display/gimpdisplay.[ch]: Removed the global "display_list"
	and "display_num" variables. Use gimp->displays instead.

	* app/display/gimpdisplay-foreach.[ch]: renamed most functions
	from gdisplays_foo() to gimp_displays_foo() and pass them a Gimp
	pointer.

	* app/core/gimpimage.[ch]: added a "flush" signal.

	* app/display/gimpdisplay-handlers.c: connect to "flush" and call
	gimp_display_flush() in the callback.

	* tools/pdbgen/pdb/display.pdb: use gimp_displays_flush(gimp)
	here and only here.

	* app/pdb/display_cmds.c: regenerated.

	* app/app_procs.c
	* app/gui/gui.c
	* app/gui/preferences-dialog.c:
	s/gdislays_foo()/gimp_displays_foo(gimp)/
