Support for symfony/twig-bridge trans filter

[jaysee]

Hello,

now that this filter is available, it could be usefull to support it ?
I actually made a simple method that extract all strings from may twig template using Symfony\Bridge\Twig\Translation\TwigExtractor then generats a fake php file with some simple gettext( 'key' ) calls, then scann it using the PHP-Scanner. But it looses the filename/line information that can be usefull

thanks
