	Preloader
	A very simple image preloader object
  
 	Usage:
 	
    Preloader.add(path);
    Preloader.onFinish(func);
    Preloader.load();
    
      path: 		A string or array of strings of image paths to preload
      func:     A function or array of functions to be called after images are loaded

      load():   Start the preloader
