comments: add scores, rework comment menu.

* Add comment scores.
* Rework voting buttons so that you can click the upvote/downvote
  buttons to toggle votes.
* Hide the edit, delete, undelete, and report buttons behind a popup menu.
* Show the upvote/downvote/reply buttons to logged out users. Redirect
  them to the login page instead.

 * You can now see the list of comments and forum posts you've reported to
   the moderators at <https://danbooru.donmai.us/moderation_reports>.
 
+* Comment scores are now visible and the vote buttons have been reworked.

 * You can now see when a post has deleted comments. Deleted comments are now
   replaced with the word `[deleted]`, instead of being completely hidden.
