To clarify IDL.

To clarify IDL.
1. It is forbiden to change input of Prs3d objects outside of "3D Cache System". So, corresponding functions are removed from IDL (but stays as it is in implementation)
2. "ScalaraMapOnDefomedShape" presentation was modified in the following way:
  a) Method
      void SetScalarField(in string theMeshName, in string theFieldName, in long theIteration, in Entity theEntity)
    was changed to the
      void SetScalarField(in Entity theEntity, in string theFieldName, in long theTimeStampNumber)
  b) Method
      string GetScalarCMeshName()
    was removed at all
  c) Method
      Entity GetScalarEEntity()
    was changed to the
      Entity GetScalarEntity();
  c) Method
      long GetScalarLIteration();
    was changed to the
      long GetScalarTimeStampNumber();
  d) Method
      string GetScalarCFieldName();
    was changed to the
      string GetScalarFieldName();
