Simplify time manager in search() Remove the F[] array which I find unhelpful and rename `improvingFactor` to `fallingEval` since larger values indicate a falling eval and more time use. I realise a test was not strictly necessary, but I ran STC [-3,1] just to check there are no foolish errors before creating the pull request: STC: LLR: 2.96 (-2.94,2.94) [-3.00,1.00] Total: 35804 W: 7753 L: 7659 D: 20392 http://tests.stockfishchess.org/tests/view/5bef3a0c0ebc595e0ae39c19 It was then suggested to clean the constants around `fallingEval` to make it more clear this is a factor around ~1 that adjusts time up or downwards depending on some conditions. We then ran a double test with this simplification suggestion: STC: LLR: 2.96 (-2.94,2.94) [-3.00,1.00] Total: 68435 W: 14936 L: 14906 D: 38593 http://tests.stockfishchess.org/tests/view/5c02c56b0ebc5902bcee0184 LTC: LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 37258 W: 6324 L: 6230 D: 24704 http://tests.stockfishchess.org/tests/view/5c030a520ebc5902bcee0a32 No functional change
