Added Company generator for ru_RU locale

you should add a `companyElement` formatter, and a list of formats looking like:

```php
$companyNameFormats = array(
  '{{companyElement}}{{companySuffix}}',
  '{{companyElement}}{{companyElement}}{{companySuffix}}',
  '{{companyElement}}{{companyElement}}{{companyElement}}{{companySuffix}}',
);
```

that's the Faker way.
