Customer wants to configure PHP Code Sniffer to work with [PHPCS Security Audit](https://github.com/FloeDesignTechnologies/phpcs-security-audit/tree/1.0.3). - they use it locally by putting the Security/ folder from phpcs-security-audit in CodeSniffer/Standards, I think we need to add it to the list of requirements in the [composer.json](https://github.com/codeclimate/codeclimate-phpcodesniffer/blob/master/composer.json)
