gnu: xorg: Add SLiM theme based on work by Felipe López.

* gnu/services/xorg.scm (%artwork-repository, %default-slim-theme,
  %default-slim-theme-name): New variables.
  (slim-service): Add #:theme and #:theme-name parameters.
  [slim.cfg]: Honor #:theme-name.
  Honor #:theme by setting the "SLIM_THEMESDIR" environment variable.
* doc/guix.texi (X Window): Adjust 'slim-service' documentation
  accordingly.  Document '%default-slim-theme' and
  '%default-slim-theme-name'.
