Subject: Searching PV first

Author: Stuart Cracraft

So I recently added some code to search the PV first
but with an add-on whose effect may be a curveball
in the longrun but appears okay at first.

PV is searched first but with the add-on that any other
position that is searched (but not on the PV) there is a check
made for whether a PV-move at the same depth is available
in this position and if so it is searched first.

Anyway, after doing the above my test results made another (small)
jump over just using the first move only of the prior iteration's
principal variation.
