@biyeun it took me a while to figure out what was going on here, until I realized that `.icon-double-angle-down` gets hijacked in css/less if it's inside an `.accordion-toggle` with `.collapsed`. This is mostly fine, except for the naming—it's so misleading!

It should really be called `.accordion-toggle-icon` or something, and then the less should have _two_ entries, one for with `.collapsed` adding the character for `.icon-double-angle-right` (as there currently is), and one for without `.collapsed` adding the character for `.icon-double-angle-down` (which is currently implicit/grandfathered behavior from the fact that you're already using this class). Thoughts?
