    Add pagination to the folder dialog
    
    Make the folder dialog's app grid horizontal, and add
    paginators to it as well. Add a new _createGrid() method
    to BaseAppView that created an IconGrid.IconGrid by
    default, and make FolderView override it to return the
    new FolderGrid class.
