Redesign the study side: Outline, Study, Script and Export stages

Studies now move through a stage bar in the reader's themes. Outline splits
chunks by clicking between verses (join merges notes) and suggests chunks from
section headings. Study is three panes: outline, passage with an Observe /
Interpret / Apply accordion, and commentary / word study / cross-refs / people
& places for the chunk; original words are added by clicking them in the
interlinear. Script drafts an outline from notes; Export holds files and the
share link. Home, Import and the Pronunciation guide are restyled. Study
projects are BSB only.
