 Use queens of either color in RookOnQueenFile 

 The recently-added RookOnQueenFile evaluation term (36e4a86) provided a bonus for placing our rook on the same file as an enemy queen. 

 Here, we relax a condition in this bonus, broadening its effect to any queen. It is also strategically desirable to place the rook on the same file as a friendly queen, so the restriction on the queen's color is removed.
