AW: Die tollen Schachprogramme von Arne Bailliere

Fixed v4.1 (with more tests I saw some engines don't understand uppercase values for "go depth" or "go nodes"; hence please set limits using lowercase for values). No change to the code, just the...

In the first version, reaching a specific depth was rather easy...

Hi all,
I simplified the triggering logic (for the GUI to apply the engine move) and made it more compliant with some UCI engines using internal books. Also, I made sure all the PV lines before...
