Commit ID d2a8ba329940655e4683a67a2528a92717700732

Simplify pseudo_legal() Big simplification of pawn move check. Code has been tested with a brute force approach: for every position reached during a bench search, the function has been called for each combinations of Move(from, to) and verified the result is the same of old code. Actually this function is very critical becuase is the one that ensures corrupted TT moves are discarded, so to properly test it a simple bench is not enough. Verified also speed is not changed. No functional chnage.
