Update WhiteNoise from 2.0.6 to 3.2

WhiteNoise 3.0 switched to a new middleware based integration approach:
http://whitenoise.evans.io/en/stable/changelog.html#v3-0

This means WhiteNoise now plays nicely with other middleware classes
such as `SecurityMiddleware`, allowing for HTTPS redirection for
WhiteNoise-served assets too.

Full documentation is here:
