RPL Global User-defined Functions -- 4-13-2009
http://cadswes2.colorado.edu/~philw/2009/GlobalRplFunctions/

Added variation of the RPL Function Icon for Global Functions 
(i.e.  Functions in Global RplSets).

------------------
QtRpl/RplIcons.hpp
QtRpl/RplIcons.hpp
------------------

New public method:
  static const QPixmap& globalFunction()  { return me()->_globalFunction; }

New private members:
  static const char* _globalFunctionData[];
  QPixmap _globalFunction;

Also, renamed these two overloaded public methods. Semantically, this overload
was reasonable, but technically, it's fragile.  I ran into a problem two times
related to the incorrect one being chosen (once because of a typo which didn't
result in a compilation error).

  OLD: static const QPixmap& getIcon (const RplObj*);
  OLD: static const QPixmap& getIcon (bool);

  NEW: static const QPixmap& getObjIcon (const RplObj*);
  NEW: static const QPixmap& getActiveStateIcon (bool);
