    main: tell Qt applications to look like GNOME
    
    If the user is logging into GNOME then QT applications run in the
    session should integrate as good as possible.
    
    According to KDE folks, the best way to achieve that is to set
    
    QT_QPA_PLATFORMTHEME="qgnomeplatform"
    
    This commit does that.
