Engine Updates

DoubleCheck 2.1 (UCI)
C source; Win64, Linux64
- for 64-bit machines only
- parametric PSQ. Based on Fruit, although the code is a complete rewrite, and
several things have been simplified. I'm trying to minimize the number of
parameters here, with a view to do a CLOP optimisation later. Number of param
in PSQ: 18+2*8+2*4=42, compared to 2*6*64=768 previously!
- polling code fixed: stop command should now work on POSIX and Windows
- drawish material recognizer: should look less stupid in dead drawn endgames!
- bug fixes: an important one being the eval "phase" casted to int (so was only 0 or 1)
