addresses ecm4u #8171: Reimplement Transformation behavior to avoid ActiveMQ messaging/events subsystems
This patch solves the problem of missing previews when uploading new document versions if messaging is disabled in Alfresco Repostiory. Since Alfresco 6.2 the creation of a new rendition for a new version is triggered via messaging (!!). The patch implements the previous behaviour via a behaviour to avoid activeMQ just for this use case.
