[gnome-color-manager] Add a --file argument to gcm-viewer to show files not yet added in colord

[Richard Hughes <rhughes src gnome org>]

commit 3449eb1f05456e5fbc26ccfade9aa3e573e5645a
Author: Richard Hughes <richard hughsie com>
Date:   Tue Aug 23 22:45:26 2011 +0100

    Add a --file argument to gcm-viewer to show files not yet added in colord
    
    To do this, we create a temp scope profile that is automatically removed when
    the viewer is closed. This lets us get the details of files that are not yet
    imported.
