	* app/display/gimpdisplay.c: added a read-only property for the
	display's image, so it can be retreived by the core, which
	treats displays as simple GimpObjects.

	* app/core/gimpcontext.c: made context->display an object
	property, not just gpointer. Connect to the "remove" signal of
	gimp->displays to get notified of disappearing displays. Removed
	the EEKWrapper and get the display's gimage with g_object_get().

	* app/widgets/gimpimagedock.[ch]: added image_dock->display_container
	and require it being passed in the constructor. Do voodoo things
	in the "image_changed" and "display_changed" callbacks to ensure
	that the dock doesn't end up with no display even if the active
	image has one. Added a style property for the image menu's preview
	size.

	* app/gui/dialogs-commands.c (dialogs_menu_update): set the
	"View as List" and "View as Grid" items insensitive if the
	other view type doesn't exist. Hide them if the view cannot
	be classified as "list" or "grid" at all. Also hide the
	"Preview Size" submenu if it's pointless for the view.

	* app/gui/dialogs-constructors.c: added a special tab for the
	navigation dialog. Will propbaby add dockable->stock_id to
	generalize this kind of tab. Pass gimp->displays to
	gimp_image_dock_new().

	* app/gui/menus.c: reordered the "<Dialogs>" factory entries,
	added more stock icons, cleanup.

	* etc/gtkrc_user
	* themes/Default/gtkrc: document usage of GimpImageDock's
	"menu_preview_height" property.
