The audit job that was failing was being triggered by a line in the _show_details template that attempted to fetch the status of the most recent audit on that object.  Since we probably don't care about showing our end users information about the internal state of Fedora I went ahead and removed it.  For the time being I've also axed the 'characterization' line, as core files by definition no longer possess this data.  That might be a candidate for reintroduction at a later date.
Merge branch 'develop' of https://github.com/nu-lts/drs into develop

Merging in a rake task change before I use that rake task, I think.
