[gnome-control-center/wip/msanchez/printers-clean-heads: 6/6] printers: Expose the newly added 'Clean' maintenance command to users

[Mario Sanchez Prada <msanchez src gnome org>]

commit 7595e057ad4b24bffdb5510ee83dfcc3e089ead6
Author: Mario Sanchez Prada <mario endlessm com>
Date:   Fri Apr 29 12:33:33 2016 +0100

    printers: Expose the newly added 'Clean' maintenance command to users
    
    Use pp_maintenance_command_is_supported() to check whether the CUPS is
    actually supported to decide when to show the new action, and implement
    the action so that it actually executes the command.
