Links in search facet items are run through url() twice

Links in search facet items are run through `url()` twice, once in the preprocess function:

```php
function culturefeed_search_ui_preprocess_culturefeed_search_facet_item(&$variables) {
  // ...
  $variables['url'] = url($variables['path'], array('query' => $query, 'absolute' => TRUE));
  // ...
}
```

... and once in the template, by calling the `l()` function, which runs the `$url` through `url()` again:

```php
  ...
  <span class="facet-label active"><?php print check_plain($label); ?> <small class="muted">(<?php print $count; ?>)</small> <?php print l('<i class="icon-remove text-red pull-right icon-large"></i>', $url, array('attributes' => array('class' => 'facet-remove pull-right', 'title' => 'Verwijder filter'), 'html' => TRUE)); ?></span>
  ...
  <?php print '' . l($label, $url, array('html' => TRUE)); ?> <small class="muted facet-count">(<?php print $count; ?>)</small>
  ...
```

This is wreaking havoc on my website's `hook_url_outbound_alter()` implementation.

In passing I also fixed an untranslated string.
