    wizard-source: Make it easier to tell download rows apart
    
    Unfortunately we are still doing a bad job at differentiating the
    "Download an OS" entries. The reason is the lack of standartization
    in the media filenames and variant classification.
    
    There's a ongoing discussion in Libosinfo to classify the "purpose"
    of a Osinfo.Media.
    
    https://www.redhat.com/archives/libosinfo/2018-November/msg00146.html
    
    For now, let's add a tooltip to the rows containing the media
    filenames.
    
    Fixes #471
