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"
speed~address to download git.aryadevchavali.com->aryadevchavali.com/resources
status/datetime~date format to a decomposed format
status/music_update_bar~pid to kill on dwmblocks
+psearch function to search pacman with less (I use this all the time,
just makes it easier to do in one go)
~speed script to use a slightly larger file so user can get a better
estimate of dl speed
~ada-mode slightly better comments
