Adjust best value in main search depending on depth This patch does similar thing to how it's done for qsearch - in case of fail high adjust result to lower value. Difference is that it is done only for non-pv nodes and it's depth dependent - so lower depth entries will have bigger adjustment and higher depth entries will have smaller adjustment.
