Short Description: Change availability of Slot Config Dialogs/Operations
Bug Number: 4980 
Release notes (y/n): Yes
For Release Nums: 5.3

Gnats 4980: Configure menu in new expression slot is disabled
SEE http://cadswes2.colorado.edu/~philw/2010/bugs/4980/

ALSO: Removal of some Flag-setter menu items in the SCT (see bottom).

Re-implementation of the "availability" of Slot Configuration and Time
Series Range dialogs from Open Slot Dialogs.  The major criteria have
been centralized in these Sim/SlotGUIUtils functions:

  bool dataEditable (const Slot*);
  bool dispPropsEditable (const Slot*); // display units, precision, format  
  bool execPropsEditable (const Slot*); // convergence, min/max, series range

One major change is that changing "Display" properties (e.g. display 
precision or units) is now possible for non-editable Slots (with some 
limitations) -- in Viewer Mode, or slots on Data Objects or Non-Scenario 
Slots in Baseline Models.  When showing a Slot Configuration in these 
cases, the following limitations apply:

 (1) When changing Units (always within the same Unit Type), there is no 
     option for "No Conversion".  Values are always "converted" (which 
     means that the underlying Standard Unit values are NOT changed).

 (2) In multiple-column Slots, only one column can be configured at a 
     time.  This was sufficient for avoiding "nailing" the Unit TYPE
     of columns on these read-only Slots. (A more precise policy could 
     be coded, but this, at least, is safe).

--------------------
Sim/SlotGUIUtils.hpp
Sim/SlotGUIUtils.cpp
--------------------

Old function removed:
  bool isEditable (const Slot*);

.. Replaced with:
  bool dataEditable (const Slot*);
  bool dispPropsEditable (const Slot*); // display units, precision, format  
  bool execPropsEditable (const Slot*); // convergence, min/max, series range

See details at http://cadswes2.colorado.edu/~philw/2010/bugs/4980/ --
also summarized here:

  // =============================================
  // Data Editable?
  //
  // (1) NO  -- Slots with RPL Expressions
  // (2) NO  -- Slots on Snapshot Objects
  // (3) YES -- Other Slots
  // (4) NO  -- Viewer Mode
  // (5) NO  -- Non-Scenario Slots in Baseline Model
  // =============================================

  // =============================================
  // Display Properties Editable?
  // ... display units, precision, format.
  //
  // (1) YES -- Slots with RPL Expressions
  // (2) YES -- Slots on Snapshot Objects
  // (3) YES -- Other Slots
  // (4) YES -- Viewer Mode
  // (5) YES -- Non-Scenario Slots in Baseline Model
  // =============================================

  // =============================================
  // "Execution" Properties Editable?
  // ... convergence, min/max, series range
  //
  // (1) YES -- Slots with RPL Expressions
  // (2) NO  -- Slots on Snapshot Objects
  // (3) YES -- Other Slots
  // (4) NO  -- Viewer Mode
  // (5) NO  -- Non-Scenario Slots in Baseline Model
  // =============================================

-----------------------
Q3GUI/SlotQDlgTable.cpp
Q3GUI/SlotQtDlg.cpp
-----------------------

(1) Client modifications for Sim/SlotGUIUtils function changes.

(2) Don't refrain from showing the Slot Configuration and Time Series 
Range dialogs only because the slot data is not editable.  Disabling of 
operations is handled IN those two dialog boxes.

--------------------------
Q3GUI/ScalarSlotCfgDlg.hpp
Q3GUI/ScalarSlotCfgDlg.cpp
--------------------------

Added method:
  updateEditability();

-------------------------
Q3GUI/SlotConfigQtDlg.hpp
Q3GUI/SlotConfigQtDlg.cpp
-------------------------

Added method:
  updateEditability();

Removed flag -- this is now computed dynamically:
  bool _editModeEnabled;

----------------------------------
Q3GUI/SlotTimeseriesRangeQtDlg.hpp
Q3GUI/SlotTimeseriesRangeQtDlg.cpp
----------------------------------

Added method:
  updateEditability();

----------------------------
QtSCT/SctConfigWidgets.ui
QtSCT/SctDialog.Handlers.cpp
QtSCT/SctDialog.cpp
QtSCT/SctDialog.hpp
QtSCT/SctModelData.Sim.cpp
----------------------------

Removal of MENU ITEMS for setting the "Surcharge Release" and "Regulation
Discharge" flags.  Those flags, like the "Set by Rules" flag, are now 
"display only" flags.  Toolbar BUTTONS for all three of those flags are 
among those that can optionally be shown -- but those buttons are never 
enabled.  They function as a "color key" to show the user-configurable 
colors for those Flags.

Removed:
  QAction* _setSurchargeRelAction;
  QAction* _setRegDischargeAction;
  void setSurchargeRel_Handler();
  void setRegDischarge_Handler();

Change in method:
  bool SctModelData::flagCanBeSetOnSeriesSlot (SeriesSlot*, char flagCh)

Also: Client modifications for Sim/SlotGUIUtils function changes.
