krino: coloured output, and --no-color

One palette type styles the plan table, warnings, headers, outcome counts,
prompt keys, undo's refused steps and krino log's (undone), from the
16-colour ANSI palette plus bold and faint only. Widths are measured on the
plain text, so columns line up; with colour off the output is unchanged.
--no-color works before or after any subcommand, as NO_COLOR does. The two
search-and-replace colourings are gone.
