1.6: Changing the timestep size of a custom slot shown on the viewer works, 
but then removes it from the viewer and nothing is shown. Removing from the 
viewer is OK, but should show the slot in an open slot dialog.

I ATTEMPTED to implement this behavior -- i.e. SHOWING the automatically 
removed slot in its own dialog, as a result of changing the slot's series 
timestep size.  See method: SlotQtDlg::slotViewer_removeUnsupportedSlots().

A comment added to this method describes the problem which prevents the 
added code from having the desired effect:

   // ***********************************************************
   // ***  Show Removed Slots in their own Open Slot Dialogs  ***
   // ***********************************************************

   // Note [Phil, RW 7.2, 8-2017]: This is the right idea (and was
   // explicitly requested by David in the Slot Viewer development review).
   // But, in the larger context in which this is relevant, it doesn't have
   // an effect because of a pretty funny reason. The Slot's Time Series
   // Configuration dialog (and not necessarily the Open Slot dialog) is
   // (typically) already open -- and THAT'S the "Slot's" dialog which is
   // found when we attempt to open "the" slot's dialog. I am checking in
   // this code, because it is "correct". But the effect would have to be
   // fixed at that other level.

   const Date_Time when = getDateTime();
   QList<BaseRWDlg*> newDlgs = QGui::openSlots (removedSlotColList, &when);
   newDlgs; // (avoid compilation warning)
