    Fix compilation with newer versions of GLib
    
    GIO now contains a GMenuItem object type.
    
    src/MainWindow.vala:300.17-300.24: error: `MenuItem' is an ambiguous reference between `GLib.MenuItem' and `Gtk.MenuItem'
    MenuItem recentFileItem = (Gtk.MenuItem)builder.get_object("menubar_open_recent");
    ^^^^^^^^
