GNU Go 3.1.7 released September 24, 2001

The release tag is rel-3-1-7.

I used the following patches in entirety:

teun_1_7.3. Sets MAX_BOARD to 19 and fixes a bug.
trevor_1_7.2. Color for Windows.
teun_1_7.2. Fixes an out of bounds violation.
inge_1_7.6. Continued one-dimensional revision.
trevor_1_7.1. Color patch.
gunnar_1_7.3. Bugfix in do_find_superstring.
gunnar_1_7.2. Bugfix and new owl tests.
gunnar_1_7.1. Bugfix and tuning.
teun_1_7.1. Fix some optarg warnings.
tuning_1_7.1. Tuning. (A change: D1132 is type 'B'.) 
inge_1_7.1. One dimensional stuff.
inge_1_7.2. More one dimensional stuff.
inge_1_7.3. One dimensional stuff.
inge_1_7.5. One dimensional stuff. 
inge_1_7.7. Converts heye structure to one-dimensional. 
inge_1_7.10. One dimensional conversion of reading.c. 
teun_1_7.4. Fixes a memory leak in gtp_loadsgf. 

The following patches were used with exceptions:

inge_1_7.8. Converts half_eye_data structure to one-dimensional. I took
            out the board iteration macros which are used in two 
            subsequent patches of Inge's since that matter is still
            being discussed.
tuning_1_7.2. I did not use the revised Joseki valuation in shapes.c
            because I haven't heard whether Gunnar objects to this.
mans_0_0.1. I used the two new functions in sgfnode.c but the
            rest of the patch is still pending.
