Builds as one slide per step when the template has Build 1, 2, ... (v1.3.2)

- Template.step_builds: build slides without ProPresenter's build feature;
  each build in the notes becomes one slide per step from the template's
  k-th build slide (last one reused): heading + first item, then one more
  line per slide; font runs cut to each step's text
- Build headings (":"/"?"/italic, or above a numbered / same-word list) kept
  as Line.lead; TextEdit format marks them with ">"
- Prefer a one-slide-per-step template over a newer old-style one
- Clear message when a notes file in Google Drive can't be read
- README: builds, underline, fonts are never changed

 Formatting always comes from the template's own sample slides. To change how something looks,
 change the template in ProPresenter and the tool follows. Templates are found by name: any
