What is this?

Improvements to WhiteNoise:

• Serve media as well as static files.
• Save media with hashed filenames, so they can be cached forever by a CDN.
• Do not crash the collectstatic management command when a referenced file is not found or has an unknown scheme.
• Add django-pipeline integration.
• Add support for Django 1.6 via monkey patching.
• Strip the Vary header for static file responses via middleware, to work around an IE bug. This should come before SessionMiddleware in MIDDLEWARE_CLASSES. See: http://stackoverflow.com/a/23410136
