7.x.select csl

Not overly concerned, but any reason not to have this in the `#attached` bit below?
Sommat like:
```php
  '#attached' => array(
    'js' => array(
      drupal_get_path('module', 'islandora_scholar') . '/js/citation_select.js',
      array(
        'type' => 'setting',
        'data' => array(
          'islandora_scholar' => array(
            'pid' => $pid,
          ),
        ),
      ),
    ),
  ),
```
