Creates a mod action any time an alias or implication is changed. This
includes creations, edits to pending aliases/implications, deletions,
and approvals. Also it logs each status change from pending -> queued
-> processing -> approved.
Call are changed from `update_column` to `update` so that the
create_mod_action callback will run at every point in the lifecycle.
There was a regression in 6d6d00b; `before_filter :voter_only` was a
no-op in the post vote controller because it merely returned false,
which does not halt the request. The fix is to arrange for a voter_only
method to be defined that properly redirects to the access denied page.
* Validates that status is active/pending/deleted/etc. Not strictly
necessary, the controller prevents users from setting the status, but
it doesn't hurt.
* Validates that forum_topic_id is a valid topic if it's present.
* Validates that approver_id and creator_id are valid users (not
strictly necessary either, users can't set these values).
vote.destroy sets the score in the database but not on the in-memory
post. So just reload the post from the db to get the updated score,
don't duplicate the logic of setting it again.
Remove start_as_gold? and start_as_contributor? from default config
because they don't actually do anything. `git log -G start_as` indicates
they never have done anything.
Add a more general customize_new_user method for setting the starting
user level, permissions and defaults for any other settings.
* Make illust_id_from_url a public class method instead of a protected
instance method so that Post#parse_pixiv_id can use it.
* Also make illust_id_from_url swallow the exception that
illust_id_from_url! throws so that parse_pixiv_id can use it.
Sadly, array index failed to cover "unset bits" case,
so excluded bits are merged into bigint, and &'d with column,
which turned out more readable and simpler than bit string.
