Test versions / private versions wanted for testing purposes

[smrf]

Especially Winboard is problematic. E.g. for random chess variants it specifies different castling notations without any need. Moreover it is not possible in all versions of winboard to set up a position. If then there is an artificially distinction between 'fischerandom', 'normal' and 'nocastle'. But there is no need for that if compatible X-FEN would be supported. Also in UCI extension for Chess960 a related compatibility error has been made, encoding identic positions differently depending on being regarded as coming from traditional chess or Chess960, which is nonsense.

Thus I intend to extend the old UCI-2 approach to compatibly widen that protocol for a combinded 8x8 and 10x8 multivariant GUI, but writing such a GUI will need a serious amount of time. There is no help. And I mainly intend to write a universal chess engine instead of a GUI.
