Not sure a this point if ImageSegment loading should be preserved
between Squeak versions. Not sure how it can be done.

I took a look at SmartRefStream instead and by using that to move my
objects I can follow the instructions in the class comment ( :) ) on how
to add conversion methods. So I am doing this now for Date and
TimeStamp.
This should of course be done for all the Chronology classes if we
really care :) - I will start by getting those two working in order to
learn this and be able to migrate my stuff.
