fo-parse-script: parse a screenplay

Plugin types: Script Writers.

Parse Script is planned, and nothing in FilmOpen calls it yet.

After FilmOpen imports a screenplay, a person may ask for Parse Script: it would propose story arcs as folders, scene breaks where times and places run together, and a synopsis of each scene, story arc and character. FilmOpen writes these only when the person applies them. FilmOpen’s own import never waits for a plugin.

A later version fills in the prompts and the choice of models.
