awk is OP man - so easy to use and does a bunch of stuff all at once
without having to rely on multiple pipes. It comes with essentially
every distribution so you'll always have access to it.
notable changes:
- rename `bt-connect` to `bt_connect`
- rename `music` to `media` and make it generic instead of checking
Spotify
- make separate script to set background to a preset black image
- make all shebangs "#!/usr/bin/env sh"
