Migration headache

[Göran Krampe]

Hi again!

Status report:

I managed to brute force myself through the problem with 
SortedCollection by converting them to OCs in the old db/image, then 
opening it up in the new image and converting back. So that is fixed.

Now I am facing a different issue - I have instances of Q2User (the user 
object in Gjallar) that now needs to "become" instance of Q2PersonalUser 
- a subclass of Q2User. Same ivars, just a refactoring of the hierarchy.

...ehm... do I need to use MagmaFileTraverser or does Magma have some 
nice hooks for picking a different class?

regards, Göran
