[Zope-Annce] Zwiki 0.52.1 released

[Simon Michael]

I've released Zwiki 0.52.1. We are aiming for a 0.52.x release that's 
extra-solid, so please keep reporting issues and I will make another 
bugfix release if needed. Thanks!

Summary

    Bugfix release.

Upgrade notes

    If you installed 0.52 in a CMF or Plone site for the first time,
    the zwiki_standard skin layer may not have been installed and some
    images may appear broken. If so, uninstall and reinstall Zwiki in
    add/remove products.
