Decrease time usage if engine has time disadvantage. This is skipped in two cases: 1. if the nodestime option is used we can't calculate the opponent nodes budget in a deterministic way. 2. if we use a cyclic time management (like 40/10) calculating time advantage for the last move (movestogo = 1) can be vastly off, because if the opponent had done his last move before us his time budget includes already the next cycle time increment but our not. This leads to a unnecessary big decrease in time usage which favors blunders.
