coffee-rails and daemons are unused.
kgio, net-ssh, and nokogiri are pulled in by other gems, but they aren't
used by us directly, so they shouldn't need to be listed in the Gemfile.
The template looks like this:
Subject:
#{creator_name} mentioned you in a comment on post ##{post_id}
Body:
@#{creator_name} mentioned you in a \"comment\":/posts/#{post_id}#comment-#{id} on post ##{post_id}:
[quote]
#{DText.excerpt(body, "@"+user_name)}
[/quote]
There's not much sense in saving copies of everything DanbooruBot sends
in DanbooruBot's inbox. They probably won't be checked so it just bloats
the dmails table.
Fixes an N+1 queries problem in the /moderator/post/queue view by
prefetching disapprovals and uploaders.
Also the way disapproval messages were previously rendered triggered a bunch
of sql queries for each post:
SELECT COUNT(*) FROM "post_disapprovals" WHERE "post_disapprovals"."post_id" = $1 [["post_id", 52]]
SELECT COUNT(*) FROM "post_disapprovals" WHERE "post_disapprovals"."post_id" = $1 AND "post_disapprovals"."reason" = $2 [["post_id", 52], ["reason", "breaks_rules"]]
SELECT COUNT(*) FROM "post_disapprovals" WHERE "post_disapprovals"."post_id" = $1 AND "post_disapprovals"."reason" = $2 [["post_id", 52], ["reason", "poor_quality"]]
SELECT COUNT(*) FROM "post_disapprovals" WHERE "post_disapprovals"."post_id" = $1 AND "post_disapprovals"."reason" IN ('disinterest', 'legacy') [["post_id", 52]]
SELECT COUNT(*) FROM "post_disapprovals" WHERE "post_disapprovals"."post_id" = $1 AND (message is not null and message <> '') [["post_id", 52]]
SELECT "post_disapprovals".* FROM "post_disapprovals" WHERE "post_disapprovals"."post_id" = $1 AND (message is not null and message <> '') [["post_id", 52]]
This refactors to bring it down to one:
SELECT "post_disapprovals".* FROM "post_disapprovals" WHERE "post_disapprovals"."post_id" = $1 [["post_id", 52]]
Sends automated dmails from `Danbooru.config.system_user`, rather than
whichever user is performing the action happens to be (usually User.admins.first).
Also adds a notice in the view that the dmail was automated.
