Ensuring creation of PREMIS event files during MakeFOXML step
Instantiating Stages object and injecting into VirusScanJob and CleanupDepositJob so that virus scan can resolve tag uris.  Count of scanned files in virus scan will now reflect the number of objects that passed rather than the number of hrefs iterated over, so that skipped files won't count
Removed null check for Stages in VirusScanJob since it is preferable to know if the job is misconfigured
Updated protected API for working with premis in deposit jobs so that getting the premis file causes it to be created
Remove comment about event document in addEventsDS since we aren't dealing with it anymore there
Merge pull request #213 from UNC-Libraries/premis-for-all
