[gnugo-devel] Eyemin patch

[bump]

There seems to be no logical reason to let *eyemin get negative in
owl_estimate_life.

This affects the regressions:

./regress.sh . nngs.tst 
720 unexpected FAIL: Correct 'F16', got 'A11'
./regress.sh . trevorc.tst 
1360 unexpected PASS!

- Never decrement *eyemin to negative in owl_estimate_life
