- Added an is_scriptable method to test applications for having

  a scripting dictionary. Made up by me, not guaranteed to be correct
  (and, indeed, Internet Explorer does not seem to play by the book).
- Added the interactive main program as a separate routine, so it
  can be called from the IDE later. Also made it less interactive by
  default: only the input app and output package folder are asked for.
