Eliminate accessible children-changed event flood during initial load
Accessible children-changed events should not be emitted during the initial load of the icon container. They should only be emitted when a user-triggered action (creation of file, copying an item) causes an item to be added.
User-triggered actions result in nautilus_canvas_container_layout_now being called, so set a flag there so that we can distinguish the two types of additions in the accessible icon-added callback.
