Title: Allowed linked resources to be opened in a new tab + minor fixes

Using the data attribute `data-new-tab` with tinymce allows resources linked through the picker to be opened in a new tab if they're not directly embeddable.

Example:

```php
$builder->add('content', 'tinymce', array('attr' => array('data-new-tab' => 'yes')));
```
