The ideal solution to this would be to have AF do this itself (as requested here https://drupal.org/node/2138817), but until that happens, I'm trying to hook into AF to add the class(es) I need, in every place they are needed.

I know I can use hook_preprocess_node() for changing where the full poll topic is actually shown, but that doesn't cover all bases. The various lists shown by AF are where the icons appear. I don't know how/where to hook into the process for that sort of change. Any suggestions would be greatly appreciated.
