Aram Tumanian 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.

STC:
LLR: 2.95 (-2.94,2.94) [-3.00,1.00]

LTC:
LLR: 2.94 (-2.94,2.94) [-3.00,1.00]
Total: 45270 W: 5737 L: 5648 D: 33885

No functional change.
