FrOSCon-Update For The TDF.templateuploadcenter

During the FrOSCon I worked on an update for the Plone add-on that will drive the New LibreOffice templates website. This update contains some aditional validations. I released it weithin the ‚Cheeseshop‘ today. The new version will be available on the testsite for the new LibreOffice extensions and templates repository within the next run of buildout.
