title: Force Django ManifestStaticFilesStorage to always return urls with hashes
body: <p>By default, <code>ManifestStaticFilesStorage</code> only returns urls with hashes in them when <code>DEBUG=False</code>. I want my development environment to be as close to production as possible, but I do need to set debug to False for a couple of things during development. Is there a way to tell <code>ManifestStaticFilesStorage</code> to always give me the url with hash?</p>
