Patterpad 0.21.0

Added

• Edit ▸ Show Card in Storyletter. When a Storyletter project nearby is paired with this Patter
  project (it names it as its Patter project), the Edit menu offers the storylet card the open scene
  belongs to, and opens Storyletter at it. The first time, if Patterpad can't find Storyletter, it
  asks you to point to it once, and remembers.

Fixed

• Opening a scene another tool has just added lands on it. Storyletter can now write a stub scene
  for a card into your Patter project, then open Patterpad at it. When Patterpad already had the project
  open, it looked for the scene in its open copy, didn't find it and stayed put. It now checks the
  project on disk, saves the scene you have open, and reopens the project at the new one.
