Use prob cut search to prune bad captures

The idea is to try a shallow search with reduced beta
on bad captures so to quickly prune them out in case
are really bad.

After 5529 games 966 - 868 - 3695  ELO +6 (+- 5.4) LOS 91%

Tested also version without upper limitation to 8 plies:

After 8780 games 1537 - 1398 - 5850  ELO +5 (+- 4.3) LOS 93%
