Include "included components" in packed versions of UI

All hail the packer. I would love to give up a few bytes to a comment before the packed JS line that said which components were packed within. When I look at a packed file a week after building and downloading it, there's no way to know if it includes, say, "draggables". Something simple like:

// jquery-ui-1.5.2 -> (UI Core, Draggable, Sortable, Slider, Effects Core, Effect "Highlight")
eval(function(p,a,c,k,e,d)....

This trend seems to be taking foot with plugin authors and the jQuery library itself when packed - still includes a bit of human readable information about the contents of the packed file. Handy info indeed!

Thanks for all the great work.
