Added option in nav_label_info to display the current page and the numbe...

...r of pages.

Very handy for paging with a specific graphic.

Example :
$('#list-example').pajinate({
        show_first_last:false,
        nav_label_info: 'Page {3} sur {4}',
        items_per_page : 4,
        item_container_id: '#paginate_properties',
        abort_on_small_lists: true,
        nav_label_prev : 'Précedent',
        nav_label_next : 'Suivant'
    });
