New extended probcut implementation

Here the idea is to test probcut not only after bad
captures, but after any bad move, i.e. any move that
leaves the opponent with a good capture.

Ported by a patch from Onno, the difference from
original version is that we have moved probcut after
null search.

Mod vs Orig: 1261 - 1095 - 5561 ELO +7 (+- 4.2) LOS 96%
