Fix listen-ereader

It didn't launch calibre properly, with the following log:

    Nov 25 12:32:23 cardano listen-ereader[802]: E-reader connected. Opening calibre
    Nov 25 12:32:23 cardano python3[5190]: qt.qpa.xcb: could not connect to display

Fix listen-ereader autostart

It was WantedBy=autostart.target, because we started that target on
sway start. Since we don't do that anymore, we now link it to
default.target, which gets started by KDE (I think? Kwin starts it?)

systemd: remove nearly everything

applications/autostart: remove

all: use stow's dot-x syntax

systemd: remove DISPLAY environment variable in sway-related units

Inspired by [0]. The sway-related part is fixed in dotfiles/cde253d9
[1]. Since we import SWAYSOCK and DISPLAY, we don't need to do that
manually in each override.conf.

Random update

listen-ereader: use go module instead of python script

I used the python script [0] that used `pyudev`, but this kept
failing. I had it hard-coded to link to a specific virtualenv, but
that had to be installed, which really is annoying, I don't like
python packaging!

Right now I use listen-ereader [1], my first Go project (built with
go-udev [2]).

Installation instructions:

    go build && cp listen-ereader ~/.local/bin/

Remove notmuch-new service

In notmuch 'G' calls 'notmuch-poll-and-refresh-this-buffer', which is
very useful and replaces the need for this, imo.

Override display and new autostart

Change sway background desktop application

Uses random-image from https://git.sr.ht/~rensoliemans/binaries/commit/dc8a758293415efad604e931e8ba5ac955cd7d47

Remove unused makefile install

I don't use notmuch-new.timer anymore.

Autostart vorta

This is automatically added by vorta whenever you enable
"Automatically start Vorta at login". Not sure if I want this tracked
but here it is.

Add mpd-mpdris

Requires https://github.com/natsukagami/mpd-mpris

Fix xdg-desktop-portal-gnome starting

Try to fix newbackground with slower restartsec

It complained about starting too soon.

Also change sway bg if image download doesn't work
