Chess Engine: BrainFish 180113 and book: Cerebellum Light 180113

BrainFish - UCI chess engine
JCER Rating=3378

Information 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 regarding the evaluation, only at a much higher skill level. Pondering is only active after the last move out of the book has been played.

The lines in Cerebellum_light.bin are in some cases reaching the late middlegame and endgame.
BrainFish is licensed unter the GPL, which includes the access code to the general book format.

Simplify verification search (#1362) 

1. avoid recursive call of verification. 
For the interested side to move recursion makes no sense. 
For the other side it could make sense in case of mutual zugzwang, but I was not able to figure out any concrete problematic position. 
Allows the removal of 2 local variables. 

2. avoid further reduction by removing R += ONE_PLY; 

Benchmark with zugzwang-suite (see #1338), max 45 secs per position: 
Patch solves 33 out of 37 
Master solves 31 out of 37

Revert to old time management (#1351) 

As many users reported some problems with new time management, and recent tests on longer time controls 
are even little in favor of old time management, this revert seems as a logical step.
