Clicking the Name, Size or Modified heading now sorts the listing in
the browser and clicking again reverses it, rather than reloading the
page with ?sort= and ?order= parameters. Names sort naturally so
v1.9.0 comes before v1.10.0, and directories stay first when sorting
by name.
The ?sort= and ?order= parameters still work for the initial order and
are shown in the heading, so existing links and custom templates are
unaffected.
