Iconfont icons are of no value to screenreader users; in our case, they get alternative text. By adding 'aria-hidden="true"' to the <span> holding the iconfont icon, we avoid the screenreader trying to announce the iconfont icon. This commit is to ensure consistency with the core across the additional_plugins repository. While I was at it, I also cleaned up the ChangeLogs, trying to establish a common pattern.
