* Include package data in distribution

* Add test from red-trivia repo, and fix package data setup

* The distribution will now include all files under any data/ sub-directory of a package, as well as all *.po files under any locales/ sub-directory (as it should have been before).

* MANIFEST.in has been simplified to comply with these changes and redbot/cogs/audio/application.yml has been moved to the data/ sub-directory to maintain consistency in how we declare package data.
