Fix for js error breaking other plugins

As many other people have commented and diagnosed, this plugin cases a JS error in Dashboard. It stops JS and breaks any other plugin or core feature relying on JS. For instance, I got blank admin screens in NextGen Gallery.

A fix is to use the built-in WP jquery-ui to replace the custom script this pluigin loads. The following components match up with the stuff in that script and should work. Anyway, no more breakage.

simple-slider.php ver. 1.2, line 43
