* harbour/source/vm/classes.c
    * updated __objHasMsgAssigned()
      + accept also symbols (@methodname()) not only strings as message name
        (2-nd parameter) just like in __objHasMsg() or __objSendMsg()
      + added suport for scalar classes in __objHasMsgAssigned()
      + generate RT error when wrong parameters are passed
    * updated comments with .prg functions syntax
