Changed the EntityManager for Doctrine ORM to getManagerForClass to make the code better understandable.
Removed the getEntityManager() function from the ORM BaseController, as it appears not to be used anywhere in the code.

fix embed type form
Fixed preg_match

We should be sure that the checked option ends with Type. 
Without that such configuration in *generator.yml:
```yml
page:
        label: ""
        formType: \NS\AdminBundle\Form\Type\BasePage\EditType
        addFormOptions:
          data_class: NS\CMSBundle\Model\Page\TeaTypePage
```
will generate such code:
```php
$formOptions = $this->getFormOption('page', new required' => false,  'data_class' => 'NS\CMSBundle\Model\Page\TeaType());
```
and of course fatal error.
