Simplify time management and fix 'ponder on' bug Simplify time management code by removing hard stops for unchanging first root moves. Search is now stopped earlier at the end iteration if it did not have fail-lows at root. This simplification also fixes pondering bug. Ponder flag was true by default and cutechess-cli doesn't change it to false even though no pondering is possible. Fix the issue by setting the default value of 'Ponder' flag to false. 10+0.1: ELO: 3.51 +-3.0 (95%) LOS: 99.0% Total: 20000 W: 3898 L: 3696 D: 12406 40+0.4: ELO: 1.39 +-2.7 (95%) LOS: 84.7% Total: 20000 W: 3104 L: 3024 D: 13872 60+0.06: LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 37231 W: 5333 L: 5236 D: 26662 Stopped run at 100+1: LLR: 1.09 (-2.94,2.94) [-3.00,1.00] Total: 37253 W: 4862 L: 4856 D: 27535 Resolves #523 Fixes #510
