Comment 1 for bug 1590536

Seems like the Categories used to be there, but no longer appear, due to this change: https://github.com/testing-cabal/testresources/commit/e9fecfc450144ba627209e82e219fddf495a3e83#diff-2eeaed663bd0d25b7e608891384b7298

It might be a good idea to move the trove classifiers, etc. back to setup.py instead of setup.cfg, because https://pypi.python.org/pypi/testresources isn't picking them up.
