AppletLoader: addded ability to use appletloader with no images, just the logo, just the progressbar or both. To set no image for either image you must set the parameter value to "". Both images are now centred independently allowing variable size logo and progressbar images. Resized appletprogress.gif to match appletlogo.png size.
