Merge equals positions

[mafutrct]

As far as I know, equal positions that arise by a different move order (or by passes) do not lead to the same database entry. That's an important feature that should by implemented to avoid doubled work.

this is a good idea -- i have this for goproblems, and it would work well in josekipedia too. it's a bit tricky right now but someday i'd like to do it.

The main advantage of this feature isn't even avoiding duplicated effort but in making sure there aren't duplicates of a position having different sets of follow up moves and being seen by different eyes. Also, someone who's an expert on a certain position shouldn't have to hunt around for every example where the position comes up.
