    gs-application: Update copyright in about dialogue
    
    The number of contributors (and hence copyright holders) is too great
    for them to be listed individually, so list them as a group. As this
    string now includes words which aren’t names, make it translatable.
    
    Update the dates too, as time continues to pass.
