inverted. This will be used with clickable column view headers.

The GtkColumnView creates a GtkColumnViewSorter at startup that it uses
for this property.

- Adds a writable GtkColumnViewColumn::sorter property
This allows defining per-column sorters. Whenever an application sets a
sorter for a column, the header becomes clickable and whenever
a header is clicked, that column's sorter is prepended to the list of
sorters, unless it is already the first sorter, in which case we invert
its order. No column can be in the list more than once.
