- Gave the package a descriptive name.
- Passed over with black once more.
- Created setup.py to install dependencies.
- Updated author to reflect repo ownership to Dusty.
- Changed `git` command to use the __url__ attribute.
- Changed music to use ogg vorbis instead of mp3, purely for
performance.
- Tried to make sure nothing broke.
- Updated dockerfile. Pretty sure we don't need it though...
