[Zope] Changing class of objects in the ZODB

[Miles Waller]

To confirm, I *just* want to change the class - attribute values, name 
and state information can remain exactly the same.

XML import/export is a good approach which I need to think about a bit 
more.  On the face of it, the data.fs is well over 1Gb in size after 
packing, and so is likely to create some issues in itself, but there may 
be ways to make this more straightforward.
