    Don't install frogr as a MIME handler for text/plain and text/html
    
    I don't know what I was thinking but this is a terrible idea, expecially
    now that we're distributing frogr as a flatpak, since the flatpak exports
    will take precedence over OS installed packages, meaning that it would not
    be uncommon that frogr attempt to open text files by default!
