Update SonataAdminBundle.pt_BR.xliff

It was missing the variable %object% in message_delete_confirmation translation from SonataAdminBundle:CRUD:delete.html.twig
Update add_block.html.twig

At the original add_block.html.twig file it was used ROLE_SUPER_ADMIN, but in the standard_layout.html.twig it is used the ROLE_SONATA_ADMIN.

I suppose that the ROLE_SONATA_ADMIN should be the global role.

At my application broke the presentation when the user has the ROLE_SONATA_ADMIN but not the ROLE_SUPER_ADMIN.

'decimal' is not allowed

Decimal is not an option for a Form in Symfony and when using it with FormMapper it raises this exception.

```
Uncaught PHP Exception Symfony\Component\Form\Exception\InvalidArgumentException: "Could not load type "decimal"" at /var/www/releases/20140521095534/vendor/symfony/symfony/src/Symfony/Component/Form/FormRegistry.php line 89 {"exception":"[object] (Symfony\\Component\\Form\\Exception\\InvalidArgumentException: Could not load type \"decimal\" at /var/www/releases/20140521095534/vendor/symfony/symfony/src/Symfony/Component/Form/FormRegistry.php:89)"} []
```
Remove non-Mopa compatibility layer when Mopa is actually installed.
Hide actions if _actions is empty

Added a replace function to check if the list is empty.

Now _actions included a string like '<li></li>' so this was never empty.
