Refactor controller injection and remove circular references

[DropSnorz]

Refactor controller architecture to match JavaFX and MVC standards for desktop UI applications.

• Controllers
  • Controllers annotated with Spring @Controller are Spring-managed and singletons.
  • Controllers loaded from Java code and outside of DI and should be called Fragments
• Services and Controllers publish events using Spring ApplicationEventPublisher for dispatching events
  • Map simple events (as refreshView() is used today)
  • Emit events from Controller and Services, use Platform.runLater() or utility FX.run() in controller listeners.
• Remove all Service->Controller and most Controller->Controller dependency injection.
• Repackage the FXML files with domain folders plugin, project, ...
• Try to remove circular dependency injection (Update application.properties flag)
