Security-Update of the four LibreOffice Plone Sites

The Plone security team published a security fix today. Thus I updated the four LibreOffice Plone sites with this security fix. Because they are all set up with a buildout I could add the security fix with only one line in every buildout-script and run it with bin/buildout -Nv again. It’s a very smooth process to add a security fix to a Plone site, if you created it by buildout.
