v1.6.0

Release Notes

• Disable marks for next moves

• Reduce memory used by loaded sgfs.
  large SGFs like Kogo's Joseki Dictionary were using almost 500MiB which
  is absurd. I have reduced the number of possible branches per node to
  mitigate this. It is unlikely someone will have more branches per node
  than 50, which is the current limit.

• Add support for showing labels

• Mark opponents turn if starting game with handicap

Bugfixes

• Completely rewrote sgf parsing. It was pretty broken for anything even slightly
  complicated before.

• Fix calloc call
  The arguments in my calls to calloc had their arguments in the wrong
  places. This might not have caused any problems at the moment, but it
  was wrong nonetheless.
