Engines: In this version 7 engines have been added, now are 47.

When analyzing a game, a tab has been added that is the Stability control. After finishing the analysis of a position with the parameters of time and depth indicated, it continues to analyze until in the last depths the calculated move is the same and the difference in the evaluation does not exceed the number of centipawns indicated. This option can add a lot of time to the analysis of certain moves. Perhaps some option must be added to control this.

This is the development version that I'm working now. Do not have many changes in relation to the version 10. These changes are mainly internal. The default tutor engine is changed from DeepFish to McBrain, both are Stockfish derivatives. Update 11.00.5a : changed the compilation, this is more compatible.
