Subject: [PATCH] Make the -L/--label argument repeatable again.

Like some of the other repeatable arguments, the switch to use
Gtk.Application argument parsing caused the `-L/--label` argument to not
be repeatable. The last use of this argument would be used as the label
for the first pane in the diff, and subsequent panes would use a default
name. Change the label argument to be STRING_ARRAY typed to allow it to
be specified multiple times.
