Noah Petherbridge a79601f983 D++ Default Author and Embedded Doodads Error
* Update native.DefaultAuthor to get the name registered from the user's JWT
  license in a way that avoids cyclic dependency errors.
* When plus_dpp.go#GetRegistration succeeds, it updates DefaultAuthor to the
  registered name. The main.go now gets and prints the registered owner to
  ensure this is populated on startup.
* Return correct ErrRegisteredFeature error when the FOSS version fails
  to load embedded doodads.
