Add paginate_with_limit helper/Twig function

Twig usage example:

```
{{ paginate_with_limit(pager, 'route_name', [10, 20, 50, 100]) }}
```

PHP usage example:

``` php
<?php echo $view['pager']->paginate_with_limit($pager, 'route_name', array(10, 20, 50, 100)) ?>
```

This will create the default pagination with a drop down list options: 10, 20, 50, 100.
