Chess engine: BrainFish 191027 and Cerebellum Light 190804

Brainfish - UCI chess engine, JCER Rating=3408

From the author:
Brainfish is a standard Stockfish chess engine extended by a general book format that is capable of handling a reduced part of Cerebellum, which is an innovative chess opening and playing book. In Brainfish, the book moves are only used in engine games, not in analysis mode.

All moves in the published book Cerebellum_light.bin generated by Cerebellum were calculated by using
Stockfish as analysis engine, without using statistics. Then those moves where recalulated by the Cerebellum Library using a graph algorithm that makes all scores in the library consistant. Consistant scores means for example, in case the starting position has a score of 0.2 and a best move is 1.e4, the position after 1.e4 must have the score -0.2. Additionally, some others properties are found, like the best main line of a position and possible Transitions.

Hence, when Brainfish is playing moves that are in the Cerebellum book, it plays like Stockfish reg…

Chess engine: Stockfish 19102601

Interesting compiled by Joost VandeVondele

Refactor final stats updates. 

This PR refactors update_quiet_stats, update_capture_stats and search to more clearly reflect what is actually done. 

Effectively, all stat updates that need to be done after search is finished and a bestmove is found, are collected in a new function ```final_stats_update()```. This shortens our main search routine, and simplifies ```update_quiet_stats```. 
The latter function is now more easily reusable with fewer arguments, as the handling of ```quietsSearched``` is only needed in ```final_stats_update```. 
```update_capture_stats```, which was only called once is now integrated in ```final_stats_update```, which allows for removing a branch and reusing some ```stat_bonus``` calls. The need for refactoring was also suggested by the fact that the comments of ```update_quiet_stats``` and ```update_capture_stats``` were incorrect (e.g. ```update_capture_stats``` was called, correctly, also …
