The biggest problem is that 'children' are stored in the file as 
sub-nodes of the parent object, and thus a version w/o this patch won't 
even see those objects that have a parent.

I could rewrite the saving/loading to store the objects the same way 
they were stored before, but I would need to have some kind of way to 
uniquely identify each object.

The cheapest solution is to just write an integer with every object and 
increment it after each object... that's not a very good solution though.


I'd be happy to change it if you have any recommendations.
