Launch EXWM directly in Emacs, instead of first launching an Emacs
server and connecting a client.
In cases where Emacs does not start correctly due to initialisation
errors the error message would never become visible without this change.
Emacs just controls everything now. Why not!
Rather than using the builtin NixOS support for EXWM I've added a
custom snippet that takes care of the launching. This assumes that the
user launching the session has my emacs configuration installed, which
I, in practice, always do.
* remove setup of i3wm (until I'm comfortable using exwm I will keep
the i3 configuration files around)
* disable compton (exwm brings its own compositor)
* disable auto-starting of emacs user service
* enable & configure exwm (also see correlating commits in my emacs.d
repository)
