Yaml component throws an exception with corrupt filename because of `json_encode`:

```
[Symfony\Component\Yaml\Exception\ParseException]
A YAML file cannot contain tabs as indentation in "\/var\/www\/app\/config.yml" at line 42 (near "	foo: bar").
```

use "translator" alias not "translator.default"

Validator is the only instance which references to the "translator.default" service. It should reference to the "translator" service so the validator can use a custom validator if the user overwrites the "translator" alias.

I've used this snippet of code to populate the default values for the en locale:

```php
for ($style = 0; $style <= 8; $style++) {
    $f = new \NumberFormatter('en', $style);
    echo 'array(';
    for ($i = 0; $i <= 17; $i++) {
        echo "'".$f->getSymbol($i)."', ";
    }

    echo "),\n";
}
```
