Title: Op warning/error display

This improves the OpDialogue so that when an Op executes successfully but emits error/warning messages in the process, they do not go unnoticed. The completion icon and message now note the problem, and the details pane is expanded to show it. This happens even if the postExecuteBehaviour requested that the dialogue be closed or returned to the parameter editor.
