[ Chris Lamb ]
* Add support for the zipdetails(1) tool included in the Perl distribution.
  Thanks to Larry Doolittle et al. for the pointer to this tool.
* Don't use parenthesis within test "skipping…" messages; PyTest adds its own
  parenthesis, so we were ending up with double nested parens.
* Fix the .epub tests after supporting zipdetails(1).
* Update copyright years and debian/tests/control.

[ FC (Fay) Stegerman ]
* Fix MozillaZipContainer's monkeypatch after Python's zipfile module changed
  to detect potentially insecure overlapping entries within .zip files.
