bring into line with Applet::list*; source compat, binary incompat. few users of this, though, and only applications, so impact is nominal. could do it in a BC way by poluting the API with another method that just takes a QString, but we stil have that sliver of a window open before 4.2.0, so use it to keep the API pristine. we can make it ugly after ;)
