Would like "optgroupRenderer" option.

Similar to the "optionRenderer" option (which I'm using), it would also be a great advantage to also have a "optgroupRenderer" option.

In my case, I'm displaying equipment within the list & show its status (green=up, red=down type of thing) by using "optionRenderer" to basically copy the CSS 'class' attribute from the original option to the generated div. Would also like to be able to do this for the cumulative group status.

== OR == even better:
Maybe you could simply append the original 'class' attribute when generating the groups/options. (then I wouldn't even need the renderer)
