Version 11.04a: Turn on the lights, calculation mode

News:

Turn on the lights, added calculation mode where the time used begins when a piece is moved, then the user can think for as long as needed, but must be accurate and fast when moving in relation to memory mode (the only way so far). also it was added an initial theme from Uwe Auerswald list of positions, where only difficulty 1 and 2 are selected.
Performance, in Options-Configuration, parameters have been added that determine the consideration of good or bad moves, as well as the degree of effect of bad moves on the total elo of a game, from 0 with no effect to 5.

Development version 11.00.09: more engines

Engines:In this version 7 engines have been added, now are 47.
I have in mind the arbitrary number of 50 engines in the windows version (in Linux is more complicated),
Norbert Raimund help me to select the next engines (that meet the limit of having a 32bit version):

Development version 11.00.06: stability control in game analysis

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.





Development version 11.00.05a

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.
