Bug: in edit mode, each time you click a thumbnail the height of the tag
edit box increases by 4px.
This is due to `scrollHeight` including vertical padding. Fix it to a)
ignore this padding, and b) ensure the min height is at least 80px.
* Fix routing error in respond_with (didn't use /moderator namespace).
* Fix /moderator/posts/approvals.json response to return full
PostApproval object, not just a success/failure message.
* Simplify the javascript a bit (use $.post instead of $.ajax).
`Danbooru.Post.approve` is used for approving posts via the mode menu.
It doesn't hide all the notices or the approve/disapprove/flag buttons.
Click the link instead to hide those things.
Click the #quick-mod-approve link instead of #approve because #approve
prompts for confirmation.
Adding a post id to a pool's post_ids string is non-atomic, hence we
must lock the pool to avoid a race condition.
Adding a pool to a post's pool_string is likewise non-atomic, hence we
must lock the post as well.
calculate_from_sample is called when clicking the General / Artist /
Copyright / Characters buttons during tag editing. Currently it's slow
because it counts up the tags in ruby, and because it makes repeated
calls to memcache in the inner loop when filtering tags by category.
This changes it to do the counting and filtering entirely in SQL using a
GROUP BY tag / COUNT(*) aggregation. This is faster and makes larger
sample sizes more feasible.

Split the wiki page versions template into two partials,
_global_listing.html.erb and _page_listing.html.erb, to avoid the nested
conditionals that arise from combining these two pages into one template.
Add html IDs to distinguish between these two partials.
