[totem] screenshot: Remove UI and flash the video instead

[Bastien Nocera <hadess src gnome org>]

commit 1249d1e8564949f4fd9c0191d1863bec5866706b
Author: Bastien Nocera <hadess hadess net>
Date:   Thu Jun 28 12:43:23 2012 +0100

    screenshot: Remove UI and flash the video instead
    
    This matches the UI used in the shell where the captured
    section of the screen flashes, and the video is automatically
    saved in the user's Pictures directory.
