Users like like posts

There's no need to group by archetype, only to filter out things the current user can't see. Ungrouping fixes an issue where the ["Likes Given" group appears twice](http://meta.discourse.org/t/likes-given-listed-twice-in-own-profile-with-wrong-number-of-likes/3230), despite the details being combined.

Also, users who can't see bookmarks shouldn't be shown the menu/count stat for it.
