Whole SGF Export on Forks

When creating a fork, if we export the SGF, it starts from where the fork does. But it would be pretty handy to have another export button for the whole SGF, i.e., from the original game on to the end. (Of course, if there are many sequential forks, it might complicate things a little.)


Not just for SGFs - I think it would be nice if the game tree were preserved for analysis as well. A lot of information is lost in a fork.
