    MoinMoin - migrate from several twikidraw files to one tarfile.

    This script looks at all pages' attachments and checks whether they
    contain TWikiDraw items. If this is the case, the TWikiDraw items are
    bundled into a single tar file (.tdraw) on the disk.
    (The intention is to later store this as a single Item in the new storage
