Bug: when moving favorites, the parent is given an upvote for each gold+
favoriter, but the magnitude of these upvotes was based on the
CurrentUser, rather than the upvoter. This meant that upvotes for
supervoter favorites weren't given correctly.
To fix this, `magnitude` is changed to use the voting `user` instead of
CurrentUser.
New problem: when setting the score, `score=` calls `magnitude`, but
`user` isn't initialized yet. So we also refactor so that
1. `initialize_attributes` initializes `user` before setting `score`
2. the vote direction is given by `vote`, so it's separate from `score`
3. updating the score on the post happens in a callback instead of
directly in `score=`.
Bug: when an approver moves the favorites of a post, each favorite is
removed from the child post and added to the parent post. For gold+
users, this triggers an upvote, but these upvotes were performed by the
approver rather than the favoriter.

Eager load post comments' creators and updaters. Fixes an N+1 queries
problem when rendering commenter names at:
views/comments/partials/show/_comment.html.erb:6
views/comments/partials/show/_comment.html.erb:20
while rendering /posts/:id pages.
Make e.g. hatsune_miku_(cosplay) automatically add hatsune_miku and cosplay.
Perform autotagging after aliasing so that *_(cosplay) aliases (e.g.
hestia_(dungeon)_(cosplay) -> hestia_(danmachi)_(cosplay)) can take
effect first.
Move normalize_tags (which processes metatags) from before_save to
before_validation. This is so that it runs as early as possible, before
strip_source / parse_pixiv_ids / updater_can_change_rating, so these
callbacks can handle source/rating changes from metatags.
Fixes a couple bugs:
* Ratings locks were ignored when using rating:s metatag (regression in 0006b76)
* Pixiv ids weren't updated when using source:blah metatag.
Note: this means that `post.update_attribute(:tag_string => "art:bkub)`
is now wrong. This is because update_attribute runs callbacks but not
validations, so it doesn't process metatags from the tag string.
`update` or `update_attributes` must be used instead.
