listbox: Optimize for sequential access

GSequence always iterates from 0 to log(N) when retrieving
the Nth element. That means writing a for-loop like this:

  for (i = 0; i < N; i++)
    row = gtk_list_box_get_row_at_index (listbox, i);

is accidentally O(n * log n). Ooops - this should be linear!

Bring the GListStore optimization for sequential access.

-/* Lists/Weather
- *
- * This demo shows a few of the rarer features of GtkListView and
- * how they can be used to display weather information.
- *
- * The hourly weather info uses a horizontal listview. This is easy
- * to achieve because GtkListView implements the GtkOrientable interface.
- * To make the items in the list stand out more, the listview uses
- * separators.
- *
- * A GtkNoSelectionModel is used to make sure no item in the list can be
- * selected. All other interactions with the items is still possible.
- *
- * The dataset used here has 70 000 items.
