Outline: per-chunk outlines, richer points, print and share

- One outline for the whole study plus one per chunk (picker at the top);
  chunk outlines can start from the chunk's verses, each carrying its words
- Points can have a type (illustration, application, quote, question,
  transition), minutes (with a running total), a longer note, verse text
  fetched from a passage, and cross-references / word studies attached from
  the chunk
- Share (system share sheet, or copy), Print / PDF, Copy as text, Word and
  Markdown downloads for any one outline
- All of it included in the Markdown, HTML/PDF and Word study exports,
  with each chunk's outline under that chunk
