New policy for consolekit.

[Daniel J Walsh <dwalsh@redhat.com>]

[-- Attachment #1: Type: text/plain, Size: 257 bytes --]

This is a new policy for the User Switching capability coming in gnome.

consolekit is a daemon that communicates with xdm_t and hal through dbus 
to change the
ownership/access on certain devices when the login session changes from 
one user to another.
