API CHANGE Installer now uses a database configuration helper class which isolates the logic of checking the database away from the installer, this interface can be used by other databases like MSSQL and PostgreSQL. The installer now looks for a specific file inside each database module, provided it's configured in install.php MySQL is provided by default, as it lives in sapphire
