Simplify away completedDepth Recent changes to this part of the code mean that the variable `completedDepth` is no longer neeeded. The only functional part of this patch is the effect on the thread voting formula. Basically, compared to master this patch raises the depth weight in the formula uniformly by 1. For very, very low depths this may have a tiny effect on thread selection compared to master. But in general we expect this patch to have no effect on game play at STC and LTC.
