fix: feet-inch dynamic input, STRETCH preselection, ribbon title wrap

- Dynamic-input fields take ' and " and read 2'9" / 3' as lengths (#937)
- STRETCH on a selection made by a crossing window stretches through that
  window and goes straight to the base point (#1068)
- STRETCH's crossing-window steps show no coordinate boxes (#657)
- Collapsed ribbon panel titles wrap at words, never mid-word (#920)
