Fix translation

Fixed a typo in the doc + Added a default translator.domains :

If someone registers its translations via yaml, he will not provide $app['translator.domains'], so pimple will raise an exeption.

I don't know if it's better to set a default $app['translator.domains'] or to checks if it set before using it.
