Accordion without icons?

http://dev.jqueryui.com/ticket/4222
"Please add the ability to use options { icons: false } to not put the
icons in the accordion. I have an accordion that doesn't use the icons
so I have to hide them with CSS currently."
Should be easy to implement (not generating the spans), not sure about
the CSS implications. Does it make sense, is it doable?
