	Implement the presistent menu of recently closed docks, still
	somewhat hackish but fully functional. Fixes bug #132744.

	* app/actions/dialogs-actions.c
	* app/actions/dialogs-commands.[ch]
	* menus/image-menu.xml.in: remove the menu items that were
	creating the hardcoded preconfigured docks.

	* app/dialogs/dialogs.[ch]: add GimpContainer of recently closed
	docks and API to load and save it.

	* app/gui/session.c: call the recent dock load and save functions.

	* app/widgets/gimpsessioninfo.[ch]: implement the GimpConfig interface
	and (de)serialize via proper interface methods.

	* app/gui/session.c
	* app/widgets/gimpdialogfactory.c: use the GimpConfig API
	to (de)serialize session infos and added the code that was
	formerly in the info's (de)serialize functions but didn't belong
	there.

	* app/widgets/gimpaction.[ch]: add "max-width-chars" property and
	set it on proxy menu item labels.

	* app/actions/windows-actions.[ch]
	* app/actions/windows-commands.[ch]
	* app/menus/windows-menu.c: add actions and menu of recently
	closed docks and code to restore the dock when the menu items are
	selected. Use above new action property to ensure a minimum
	width of the menu.

	* app/widgets/gimpmenudock.c: use '-' instead of '|' for
	separating notebooks in the window title. Menu items don't like	'|'.

	* app/widgets/gimpdock.c: removed the confirmation dialog when
	closing docks and simply add them to the recent docks container.
	This code is totally misplaced and will move to another file soon.
