    wizard: Present OS logos
    
    If we have the logo for an OS, use it to represent it at the 'Source' and
    'Preparation' pages. Because of legal implications we must get explicit
    permissions from each OS vendor to use and ship their logo.
    
    Thanks to Karen Sandler and Fedora legal for prompt action on prividing
    detailed but clear advice on usage of trademarks and logos. The following
    email nicely summarizes the whole issue with trademark usage:
    
    http://lists.fedoraproject.org/pipermail/advisory-board/2012-February/011360.html
    
    Currently we have Debian, Fedora and Ubuntu logos. We have been given
    explicit permission for each logo by their respective trademark owners
    except for Debian's, for which its policy seems too liberal to require
    any permission: http://www.debian.org/logos/
    
    Hopefully we'll soon have the permission to use Red Hat logo too. If
    someone can tell me who and how to contact for Windows logos, do let me
    know please.
