Delete Metadata version

1. Important: Only delete versions, if they are not yet used (e.g. DOI) or linked (e.g. externally distributed link)!!!
2. Important: Do not change or delete directly in the database without a current backup!
3. Important: Keep in mind deleting a version changes the current version number.
4. Important: Dueto some cached values in NHibernate session it can be necessary to restart the Server (Application pool)
