refactor: better modularise arturm/configs/qutebrowser

There are other changes too, such as some tiny refactors to make some things a
small bit more readable. For example: I added a variable in
`cityseventeen/apps.nix` to make environment variables a small bit easier to
read. It is pretty much the same case in `cityseventeen/themes.nix` except I
used map to get each attribute set with package instead of mapAttrs.

There are also some minor tweaks here and there but it isn't worth talking
about.
