Certain parts of comment rendering triggered sql queries that we didn't really need to do. Rework things to avoid this. * Preload comment creators in order to display commenter names with link_to_user. * Preload comment votes in order to display "undo vote" links. Only preload votes for members since anonymous users can't vote and don't have "undo vote" links. * Rework various conditionals to do the filtering in Ruby so that we avoid issuing any extra queries in sql. * Avoid issuing any queries at all when the post doesn't have any comments (when last_commented_at is blank).
