  Update 1.32 Analysis Board Rework

  As many use this feature, I decided to postpone working on Alekhine's games and instead spend a week upgrading the Analysis Board. The old code bad to say the least, so I basically redesigned everything from scratch. I made a new UI entirely:New features:Multiple engine lines are now Supported:Edit:As of now, Stockfish 17.1 is now bundled Chess Tools. I previously didn't do it for legal reasons because you need to make your source code public under their license. However if you simply link the exe externally and don't modify the code, you can simply link to where to get Stockfish and not have to make your whole game source code open source.So in analysis you have the option to use Stockfish 17.1 or your custom engine of choice, say if you want to use Leela or something. In Play mode, you will still go against my engine but I might make stockfish an option in the future too.Game ReviewThis is similar to before but more improved. It should be a lot more reliable now.The review will use the engine you have currently chosen, either default or custom. Then you Run Review and wait for it to finish. After you will see the score graph and a count of inaccuracies and blunders.Icons will now be shown on the board, as well as in the log. You can disable this in the review section.Currently only inaccuracies and blunders are shown, as they are a lot simpler to implement.Full customisable blunders and inaccuraciesInstead of just hard coding the values, I tried to make them as customisable as possible: -Inaccuracies go from 0.3 to 1.5 points-Blunders go from 1 to 3.5 pointsSo if you want it to be lenient and not nit-pick every possible drop in score, you can do that.And if you want it to criticise everything, like a masochist, then you can do that also.Still Winning ThresholdAnother setting is the still winning threshold. This is basically for when it shouldn't matter if you play a slightly inaccurate move. This goes from 3, 4, 5, 6 or none.Basically how this works is that if you...
