na-tray: wide panels, convert main GtkBox display to GtkGrid
New grid sorting/display functions to arrange notification area icons in a self reorganising grid main changes in: item_added_cb(), notification_notify() -> refresh_notify(). update_size_and_orientation() is no longer needed the grid auto arranges on any size-allocation which includes orientation changes. Grid is now refreshed with refresh_grid()/determine_grid_properties()/reorder_items_with_data(). based on the min_icon_size property the main applets' code can call na_grid_set_min_icon_size() to update the grid icon size.
