[gnome-media] Show the number of inputs/outputs for a device

[Bastien Nocera <hadess src gnome org>]

commit 14d69e157f531feefac5ec6c66d63514a2d113a1
Author: Bastien Nocera <hadess hadess net>
Date:   Fri Jul 24 01:42:39 2009 +0100

    Show the number of inputs/outputs for a device
    
    on the status line. Makes it a wee bit more useful than
    just showing "Ready" :)
