- Assign the temp id in 'beforeAnnotationCreated'
- Thread annotations after loading so that they have a `thread`
  property.
- Don't reference threading directly in `setupAnnotation`, instead

  events in Annotator for the Threading plugin to be fully automatic.

fixes #158

- Because of that the client does not get back to correct id.
- Added error handling for displayer page for invalid ids.
