Type: Kinsoku Set — Hard (today's set), Soft and None (#633)

Paragraph panel › Kinsoku Set (with the East Asian options) and `text.setFormat {kinsoku}`, as
decided in #633:

- Hard: today's set, so existing documents don't change; the default, and not saved.
- Soft: as Hard, except that 々, the prolonged sound mark ー (JLREQ cl-10) and small kana (cl-11)
  may start a line: JLREQ's level 3 line-breaking rules (Appendix C.3). Half-width forms aren't in
  those classes and stay off the line start.
- None: no kinsoku.

The setting reaches every break the composers consider (greedy, every-line and hyphenation
points). Reset Panel returns to Hard.

+## Kinsoku Set
+
+`text.setFormat {kinsoku: "hard"|"soft"|"none"}` sets the Paragraph panel's Kinsoku Set of the selected type (or `ids`):
+which Japanese characters may not start or end a line. **Hard** (the default; new type and documents from before the
+setting) keeps closing brackets, commas, full stops, middle dots, iteration marks, the prolonged sound mark ー and small
+kana off the line start, and opening brackets off the line end. **Soft** lets 々, ー and small kana start a line, as
+JLREQ's level 3 line-breaking rules do (https://www.w3.org/TR/jlreq/#addendum_a3); the rest of the set stays.
+**None** applies no kinsoku. `hard` isn't saved. One undo step.
