From Bertrand:

 - log level change is now reflected in the session status tab.
 - removed par files option query from edit tab and edit dialog.
 - the button in the edit tab is "Apply changes" when not connected
   and "Submit" when connected. Automatically switch to "Status"
   tab when user clicks on "Submit".
 - add total processed data to status tab.
