Dynamic config loading

- Move settings, defaults and dbstructure to directory 'static'
- Dynamic loading of config files (after the static loading)
- Filter out '-sample.config.php' and '-sample.ini.php' files
- Remove unnecessary ConfigFileManager
- Move ConfigFileLoader to Utils
- Add tests for multi-loading for INI, config and sample-filtering
