Improve comments about DEPTH constants Also "fix" movepicker to allow depths between CHECKS and NO_CHECKS, which makes them easier to tweak (not that they get tweaked hardly ever) (This was more beneficial when there was a third stage to DEPTH_QS, but it's still an improvement now) closes https://github.com/official-stockfish/Stockfish/pull/5205 No functional change
