No Tempo for draw scores given by heuristic functions The current master applies Eval::Tempo even to leaves evaluated as draw by some of the static evaluation functions of endgame.cpp (for instance KNN vs K or stalemates in KP vs K). This results in some lines being reported as +0.07 or -0.07 when the terminal position has reached such endgames (0.07 being about the value of a tempo for Stockfish). This patch does not apply Eval::tempo to these positions. This leads to more nodes being evaluated as VALUE_DRAW during search, giving more opportunities for cut-offs in alpha-beta.
