title: Using App::uses (instead of App::import) in a CakePHP 2.1 Plugin
body: <p>I'm writing a small application in CakePHP 2.1, and I want to use Nick Baker's file upload plugin. I downloaded the cakephp2.0 branch (I know that isn't done yet), and placed it in my apps Plugin folder. I made some necessary modifications on it, but I'm curious what the right way is to replace those <code>App::import</code> function calls (at start of <code>FileUploadComponent</code>, <code>FileUploadBehavior</code> and <code>FileUploadHelper</code> classes) with the <code>App:uses</code> function.</p>
  
  <p>It needs to import the <code>FileUploadSettings</code> class from Config/file_upload_settings.php and the <code>Uploader</code> class from Vendor/upload.php. It can be done with the <code>require_once</code> function, but I'm sure there is a CakePHP way to do it.</p>
