New easy move implementation Spend much less time in positions where one move is much better than all other alternatives. We carry forward pv stability information from the previous search to identify such positions. It's based on my old InstaMove idea but with two significant improvements. 1) Much better instability detection inside the search itself. 2) When it's time to make a FastMove we no longer make it instantly but still spend at least 10% of normal time verifying it. Credit to Gull for the inspiration. BIG thanks to Gary because this would not work without accurate PV! 20K ELO: 8.22 +-3.0 (95%) LOS: 100.0% Total: 20000 W: 4203 L: 3730 D: 12067 STC LLR: 2.96 (-2.94,2.94) [-1.50,4.50] Total: 23266 W: 4662 L: 4492 D: 14112 LTC LLR: 2.95 (-2.94,2.94) [0.00,6.00] Total: 12470 W: 2091 L: 1931 D: 8448 Resolves #283
