This adds tooltips to images that can show up in review lists. For everything except unstarred reviews, the existing alt text is used, for unstarred reviews "Click to star" is used.
Created reviews and comments to get the different icons to show up, saw that they had appropriate tooltips. Starred and unstarred a review to make sure the title was getting properly updated by js.
