Add a colons kind to the rule under titles, and stop its label wrapping

The design form's hint on "Rule under titles" wrapped to three lines and
pushed the select below its neighbours; it is a note under the row now.
"Colons" is a row of ":" (a long string in an ::after, clipped to the
title's width), the look of the reference site's dotted borders in text.
