[Zope] merge two ZODB

[smoerk@gmx.de]

I didn't try MpuntedStorage, because it requires ZEO. MountedFileStorage
doesn't work with my Zope 2.5.1. I get the following error:

Zope Error

Zope has encountered an error while publishing this resource.

Error Type: You can only provide an id when creating!
Error Value: None
