[Javascript] Disable or "grey out" fieldsets in a form

http://www.digital-web.com/features/feature_2003-05b.shtml describes my 
script to do this even better. It doesn't gray out form fields, it entirely 
removes them until the user requests them by, for instance, clicking on a 
checkbox.

Works in all modern browsers and is VERY easy to implement.
