MadChess 2.0 Beta Build 025 (Time Management)

I added code to measure the time taken to search each ply and calculate if enough time remains to search the next ply. This lessens the number of searches that must be abandoned in the middle of a ply, and the best move from the prior ply played. These abandoned searches waste time.

This added 24 ELO to the playing strength of MadChess 2.0 Beta. I believe improved time management will pay greater dividends once I add search reductions and pruning of moves.
