Aram TumanianandMarco Costalba 9eccba7761 Fix the pawn hash failure when the pawn key is 0 ...

This patch fixed bugs #859 and #882.
At initialization we generate a new random key (Zobrist::noPawns).
It's added to the pawn key of all positions, so that the pawn key
of a pawnless position is no longer 0.
