Title: Add topics.loaded event to be triggered when new topics are loaded by infinite scroll.

Similar to how ```action.posts.loaded``` is fired when posts are loaded, I needed an event for when topics are loaded in order to update a Masonry layout for topic pages. This would be useful for themes that want to use Masonry layouts for topics.
