    installer: Desktop environment page now includes window managers.
    
    * gnu/installer/services.scm (<system-service>)[snippet]: Change to be a
    list of sexps and add default value.
    [packages]: New field.
    (%system-services): Adjust 'snippet' fields to be lists of sexps.
    Add Openbox, awesome, i3, and ratpoison.
    (system-services->configuration): Adjust 'snippet' handling.  Honor
    'packages' field.

Maybe openbox and ratpoison services should not be suggested by the
Guix System graphical installer, because they apparently are unusable
without further config files.  Note that sway is not among the
suggested desktop environments either.  WDYT?

Florian
