[gnugo-devel] revised surround patch

[bump]

I posted a revision to my safety patch at devel.html.

This revision of safety_3_10.1a changes one thing: a dragon is
not considered surrounded if an ikken tobi jumps out. This is
necessary because an ikken tobi is often not a connection but
in practice often just as good as one.

After this patch, the surround status is a dragon2 field
and is computed for every dragon on the board. The time
required for this is negligible---usualy less than 0.01 sec
on a celeron 433.
