Each Run Param config change was raising Diag Output after a Run Abort [6031]
Bug Number: 6031
Release notes (y/n): Yes
For Release Nums: 7.1.5 and 7.2

"Run State Change" notifications were being received by the DiagOutputWidget::
runStateChangedHandler() method even for Run Parameter configuration changes.
This was causing the Diagnostic Output Window to be raised (e.g. even when 
just stepping an integer spinner in the Simulation Run Parameters dialog).

This has been addressed as follows.  Specifically when in the Run Info 
"Aborted" state, if the RiverWare Callback Type associated with this 
notification is NOT one corresponding to an actual Run Abort incident (and, 
for example, not just a configuration change) then we SKIP the normal Run 
Abort processing (which includes raising the Diagnostic Output window).

See change in method: DiagOutputWidget::runStateChangedHandler().
