- Started to weaken tab presenter's dependencies on the 'main window'
  presenter.
- Split out part of the main window presenter and view's functionality
  into ReflBatchPresenter.
- ReflBatchPresenter is currently different from the soon-to-be-renamed
  BatchPresenter. ReflBatchPresenter is a presenter which contains a
  runs, settings, events and save tab but which is not the main window
  presenter.
