    shell: Don't use the OnlyShowIn/NotShowIn flags from desktop files to hide panels
    
    It was added in 3e04b1c53b to allow downstreams to hide panels that don't make
    sense in their environment. Later on the ability for panels to hide themselves
    was added in a78cbe3963, which is a better solution for this case.
    
    The current situation is confusing if you are not a known environment, as then no
    panels show.
    
    Fixes #163
