I am a big supporter of the approach to indent with tabs and align with
spaces. (Read [here][1] f.e.) Thus at some places a simple `s/ {4}/\t/g`
(replace 4 with whatever fits) is not enough and a bit more thought is
needed. Because of that there are still places where I plan to
substitute the whitespace in the future.
This patch contains exclusively whitespace changes. Check for yourself
with `git diff --ignore-all-space`.

Wrap lines at 80 columns where appropriate and I had the energy to think
about how/where to wrap.
There are still lines longer than that, which I plan to wrap in the
future. But that is enough for now.
Instead of hardcoding the paths of all the scripts, use env variables
that are set in launch.sh. This way the config also works with
XDG_CONFIG_HOME not set to ~/.config.
Sadly polybar only accepts references that stand on their own.
(So something like ${env:XDG_CONFIG_HOME:~/.config}/polybar/<script>
does not work.) Hence the mess with the associative array and the
variables for every module.
