services: xorg: Allow users to specify a list of modules.
* gnu/services/xorg.scm (%default-xorg-fonts): New variable. (xorg-configuration-file): Add #:modules and #:fonts. Rewrite to return a 'computed-file' that honors MODULES and FONTS. (xorg-wrapper): Pass #:modules to 'xorg-configuration-file'. (xorg-start-command): Add #:fonts. Pass #:fonts and #:modules to 'xorg-configuration-file'. * doc/guix.texi (X Window): Adjust documentation of 'xorg-start-command' and 'xorg-configuration-file'.
