- The current architecture is inherently insecure, because you can construct the 'secret' cookie value with values that are available in the database. Thus provides zero protection when a database is dumped/leaked. - This patch implements a new architecture that's inspired from: [Paragonie Initiative](https://paragonie.com/blog/2015/04/secure-authentication-php-with-long-term-persistence#secure-remember-me-cookies). - Integration testing is added to ensure the new mechanism works. - Removes a setting, because it's not used anymore.
