AppletLoader: slight tweak to make code more readable

AppletLoader: removed dead code.

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.

AppletLoader: actually fail with error message if logo images are not found or an error occurs when they are loaded, added missing MediaTracker step. Also prevent paint thread from null pointer exception when this happens.

AppletLoader: fix error message so that it actually uses the error message string.
