Breaking changes from previous version

• Item skipping has changed.
  This means that if your Modifier event listener throws an ItemSkipException it will not be caught.
  Please use ItemSkipper::skip(ItemPipelineEvent $event, $reason = '') to skip items.
• AbstractImportModifyEventListener definition has changed.
  Abstract protected function modify now accepts two parameters:
  (AbstractImportItem $eventItem, ItemPipelineEvent $event).
  Please update your modifiers extending AbstractImportModifyEventListener class accordingly.
