Introduces non-server home-manager configs

Allows home-manager configs to be done on a server/non-server basis

Provides an example config by moving emacs to its own space (behind a
lib.optionals so only non-server machines accept it)

marks artemision and rhapsody-in-green as explicitly non-server machines
