Joona Kiiski 3fd0079807 Less aggressive move count based futility pruning ...

This patch from Joona greatly reduces move count pruning,
below is the old and new move count limits starting from
ONE_PLY with half-play increment:

Old: 4,5,5,5, 7, 7,11,11,11,19,19,19,35,35
New: 4,5,7,9,12,15,19,23,28,33,39,45,52,59

Surprisingly results are even a bit better at a quite
fast time control.

After 5260 games at 30"+0.1
Mod - Orig:  864 - 806 - 3590  ELO +3 (+- 3.8)
