Added multi search + compacted file with indent 2

Added ability to have the loader search not one file with the same name but others aswell for example
private static function loadConfig($file) {
    $files = Loader::multi_search('config'.DIRECTORY_SEPARATOR.$file);
    if($files) {
      // Fetch valid configuration array.
      // Cache will prevent multiple includes.
      // In the event that it does not, honor the load.
      foreach($files as $fn) {
        include ($fn);
        // Cache configuration contents.
        if(isset($config) && is_array($config)) {
          self::set($file,$config);
        }
      }
    }
  }
when passed rewrite will scan for example /system/config/rewrites.php and also /packages/*package/config/rewrites.php
