Ready for the first iteration of review.

  • Changed bodyTopEditor in the review dialog view to use the created view, dragged and dropped a few files.
  • Manually tried adding multiple files to a DnDEditorView
  • Observed and recorded expected behaviour when a file dragged over both a window that has a DnDEditorView in focus and one that does not.

Extensive testing won't be possible until the backend stuff has been implemented.
