RPL Global User-defined Functions -- 4-30-2009 (b)
http://cadswes2.colorado.edu/~philw/2009/GlobalRplFunctions/

Two changes to the RplApplication::Type properties of RplObjs, 
RplExpressions and ValueConstraints.  

These are related to the new dynamic application type override mechanism 
needed for evaluation of Global RPL Functions. Global Functions and related 
entities have the "GLOBAL" RPL application type, but during evaluation, 
the caller's RPL application type needs to be used. 

(1) The "static" RplApplication::Type property is now characterized as 
 "local" rather than "owner".  (Using "static" was awkward because the 
 _dynamic_ override property was implemented with _static_ variables and
 methods).

(2) The getApplicationType() methods (in three classes) now return the 
 dynamic override value ONLY IF the local application type is "GLOBAL".
 It was expected that the dynamic substitution would be active only on 
 such entities (global) -- but it's safer to explicitly restrict the 
 the mechanism to global RPL entities.

-------------------------------

  OLD: RplApplication::Type _ownerAppType;
  NEW: RplApplication::Type _localAppType;

  OLD: inline RplApplication::Type getOwnerAppType() const;
  NEW: inline RplApplication::Type getLocalAppType() const;

Changes to calls to this method in files:
  QtRpl/RplBaseDlg.cpp
  QtRpl/RplBlockDlg.cpp
  QtRpl/RplDlgMgr.cpp
  QtRpl/RplFrame.cpp
  QtRpl/RplFunctionDlg.cpp
  QtRpl/RplGroupDlg.cpp
  QtRpl/RplListView.cpp
  QtRpl/RplSetDlg.cpp
  Q3GUI/LoadSaveMgr.cpp

Changes to these three public methods.  These now consider the dynamic
application type substitution only if the local application type is "GLOBAL":

  inline RplApplication::Type RplObj::getApplicationType() const
  inline RplApplication::Type RplExpression::getApplicationType() const
  inline RplApplication::Type ValueConstraint::getApplicationType() const
