Possibly unused middleware: nplusone

[jchristgit]

We include the nplusone dependency, but we don't seem to use it as a middleware. Is this intentional, possibly due to performance problems?

See the official documentation at https://github.com/jmcarp/nplusone

[jchristgit]

We also use django-querycount which seems to do a similar thing: https://github.com/bradmontgomery/django-querycount
This is installed in the middleware, though.

@jerbob you originally added this dependency, do you know why we don't have it configured?
