modfications:
futility added ("fut")
special pawn capture extensions near the king when the king is on the last rank
noted as "pc" in the extension setting..
special "better move search extensions" ("ft")when other extensions are
happening with a move that is high in the search order...
improved usage of optimazations with compiler (P3 code is faster than P4 code on
P4 machines - don't ask me why)
