Remove the `category_name` field from the `/wiki_page.json` API. This
field was originally added only because it was needed by our autocomplete
Javascript. It was also misnamed, it wasn't the tag's category name, it
was the category's ID.
Users should use `https://danbooru.donmai.us/wiki_pages.json?only=title,tag`
instead if they need this.
This triggered a N+1 query pattern when dumping wiki pages to BigQuery,
which made dumping wiki pages very slow. It also meant this field was
included in the database dump, even though it wasn't a real database
column.
- The types are:
-- Previous: The default and the previously used type
-- Subsequent: Compares against the next version
-- Current: Compares against the current version
- Allow switching between comparison types in index and diff views
-- Have links vary depending upon current comparison type
- Diff view changes
-- Only show pool description changes in diff view
-- Conditionally render diff link when applicable values are changed
-- Conditionally show diff view sections when values are changed
- Show renames on index view
-- There is plenty of space
-- This wasn't shown at all for wikis
-- Having to navigate to an alternate page is unwieldy for pools
- Show "posts" as a status on pools
-- This is so all changes among versions are quantified as a status
- Standardize diff/index titles
- Changed to using the diff-body CSS class
-- Removed unnecessary elements from the CSS style file
- Does a symmetric difference on the array fields to detect differences
- Add more descriptors to the status/changes column
- Specifically add <br> to statuses to cause line breaks
Allow all users to view and edit artist entries and wiki pages belonging
to banned artists. There was little need to hide these pages from
Members, it was mainly to appease artists who didn't like us even
linking to their sites.
These restrictions also had multiple flaws:
* Banned artist information was still visible in the API.
* It was still possible to edit banned artists using the API.
* It was still possible for unprivileged users to revert banned
artist entries or wiki pages to previous versions.
* The restrictions were inconsistent: in various places they were
either Member-only, Gold-only, or Builder-only.
* Factor out common sidebar layout template.
* Convert wiki pages and posts to use this template.
* Add data-layout attribute to <body> element indicating the current layout.
It seems that in Danbooru 1 wiki page version's created_at was always
the initial created_at of the wiki page itself, as opposed to the time
that the edit was made like in Danbooru 2.
