The novel template becomes the intended layering: collection novel_template
lists my_novel_game (its own scenes, scenarios, text), town_pack (reusable
backgrounds and the bar ambience) and the engine. The town entrance and the
home vestibule move from cthangover_game into town_pack instead of being
copied; cthangover_game depends on it. Docs explain how to start a game from
these three layers.
