Short Description: Open RplSet Usability Enhancements 
Bug Number: 5113
Release notes (y/n): Yes
For Release Nums: 6.1

Addition of "Show Open RplSet" buttons to Workspace status bar.

This is an extension to the enhancements made last week to address 5113.
SEE: http://cadswes2.colorado.edu/~philw/2011/bugs/5113/

For consistency, NOW status bar buttons are ALSO shown for the following
three "built-in" RplSets -- but only if they are not empty (i.e. having
at least one RplGroup):

  (1) Expression Slot Function Set
  (2) Iterative MRM Rules Set
  (3) Initialization Rules Set

Also, when Accounting is enabled, a button is shown for:

  (4) Object Level Accounting Method Set

Additionally, the new RplSet buttons are NOT shown for the "Loaded"
RplSets (which are supported by the existing larger Workspace statusbar 
buttons -- one for "RBS" and one for "OPT").

TECHNICAL: To avoid additional coupling between QtRpl/RplDlgMgr and
Q3GUI/Workspace, a notification of a RplSet Edit Change is routed 
through a Q3GUI/QGui function. (QtRpl/RplDlgMgr already uses QGui).
This notification is needed to dynamically show or hide buttons for 
the built-in RplSets, i.e. depending on whether or not those RplSets
have any RplGroups.

-------------------
Q3GUI/Workspace.hpp
Q3GUI/Workspace.cpp
-------------------

Changes to method: Workspace::rebuildOpenRplSetButtonBox().
  - Exclude LOADED RplSets (RBS and/or OPT).
  - Force instantiation of Accounting RplSet if Accounting is enabled.
  - Conditionally create buttons for existing RplSets of these types:
      RplApplication::UDAM (Note: Misnamed. should be "OLAM").
      RplApplication::SLOT_EXPR
      RplApplication::MRM
      RplApplication::INIT_RULES

New method:
  void rplObjEditNotification (RplObj*, RplSet*, int rplEditType);
  .. calls rebuildOpenRplSetButtonBox() when receiving RPL_EDIT_ADD
  .. and RPL_EDIT_REMOVE notifications of RPL_GROUPS (to/from a RPL_SET).

Method rebuildOpenRplSetButtonBox() is now also called from these methods:
  Workspace::enableAccountingChange()
  Workspace::loadedRbsRplSetButton_clicked()
  Workspace::loadedOptRplSetButton_clicked()
  Workspace::callbackHandler (CallbackType, CallbackData*) - WS_MODEL_LOADED
  RPL_SET_LOADED and RPL_SET_UNLOADED events in:
    Workspace::rbsRuleSetMgrCallbackHandler (CallbackType, ..)
    Workspace::optSetMgrCallbackHandler (CallbackType, ..)
    Workspace::gblSetMgrCallbackHandler (CallbackType, ..) -- for completeness
    
-------------------
QtRpl/RplDlgMgr.cpp
-------------------

Method RplDlgMgr::updateDlgs (RplObj*, RplSet*, RplEditType) now calls
 QGui::notifyWorkspace_rplObjEdit (rplObj, rplSet, (int) editType);

--------------
Q3GUI/QGui.hpp
Q3GUI/QGui.cpp
--------------

New function:
  void notifyWorkspace_rplObjEdit (RplObj*, RplSet*, int rplEditTypeInt);
  ... calls Workspace::rplObjEditNotification (RplObj*, RplSet*, int);
