	* app/actions/window-actions.[ch]: connect to GdkDisplayManager
	and automatically add/remove move-to-screen actions when
	displays are opened/closed.

	* app/menus/window-menu.c: added similar code here to add/remove
	menu items for the above actions.

	* app/actions/Makefile.am
	* app/actions/window-commands.[ch]: new files containing window
	close and move-to-screen callbacks. There is no need to implement
	these twice for GimpDock and GimpDisplay.

	* app/actions/dock-commands.[ch]
	* app/actions/view-commands.[ch]: remove the callbacks here.

	* app/actions/dock-actions.c
	* app/actions/view-actions.c: changed accordingly.
