Open Slot Dialogs Initialization Settings: Sel States / Notes / Description [6]
Bug Number: n/a
Release notes (y/n): no (not this commit, but close).
For Release Nums: 6.8

Squash merge of early development. This feature is actually provisionally 
completed, but needs a full code review and more testing.

Previously, these Slot Dialog settings had effectively been cleared each 
time the Slot Dialog was re-shown (closed and re-opened):

  (1) The Selection Statistic Panel was hidden.
  (2) The "Notes" column was hidden.
  (3) The Description Panel was hidden.

With this enhancement, there is a global setting, saved with the RiverWare 
Model, which provides defaults applied each time a slot dialog is re-created.
The "Notes" and Description Panel settings have an option to show the 
feature only if the Slot contains notes or a description.  Also, for initial 
Description Panel visibility, there are separate settings for Slots on Data 
Objects and Other Slots.

Note that, currently, Selection Statistics are not supported (at all) on 
Table Slots (including Table Series Slots).  Also, Notes are supported only 
on Series Slots.

The new configuration dialog is currently accessible from (only) the 
Workspace's Workspace >> Slots submenu.  The main purpose of that dialog is 
to set the global initialization settings.  But it also provides a push 
button to immediately apply those settings to all currently-open Slot dialogs.

   Q3GUI/SlotDlgDefaultsDlg.hpp
   Q3GUI/SlotDlgDefaultsDlg.cpp
   Q3GUI/SlotDialogDefaultsWidgets.ui

The SimWorkspace maintains a single instance of the following new 
configuration data structure:

   Sim/SlotDlgDefaults.hpp
   Sim/SlotDlgDefaults.cpp

enum ShowState : char
{
    Show_Off     = '0',   // off (zero)
    Show_On      = '1',   // on (one)
    Show_Present = 'P'    // show if relevant values present
};
   
ShowState _showSelStats;         // Show Selection Statistics (on or off)
ShowState _showNotes;            // Show Notes
ShowState _showDescrip_DataObj;  // Show Description (Data Objects)
ShowState _showDescrip_SimObj;   // Show Description (Other Objects)
   
Serialization example (XML):
   
 <SlotDlgDefaults>
    <ShowSelStatus show="1"/>
    <ShowNotes show="P"/>
    <ShowDesc_DataObj show="P"/>
    <ShowDesc_SimObj show="P"/>
 </SlotDlgDefaults>
