Fix images on the upload page appearing stretched (having the incorrect aspect ratio) when the image
is enlarged on Safari.
The fix is to set `aspect-ratio` and `height: intrinsic` to ensure the image is the right size. I
have no idea how this works or why it's necessary on Safari.

Fix bug where it was possible to submit blank text in various text fields.
Caused by `String#blank?` not considering certain Unicode characters as blank. `blank?` is defined
as `match?(/\A[[:space:]]*\z/)`, where `[[:space:]]` matches ASCII spaces (space, tab, newline, etc)
and Unicode characters in the Space category ([1]). However, there are other space-like characters
not in the Space category. This includes U+200B (Zero-Width Space), and many more.
It turns out the "Default ignorable code points" [2][3] are what we're after. These are the set of 400
or so formatting and control characters that are invisible when displayed.
Note that there are other control characters that aren't invisible when rendered, instead they're
shown with a placeholder glyph. These include the ASCII C0 and C1 control codes [4], certain Unicode
control characters [5], and unassigned, reserved, and private use codepoints.
There is one outlier: the Braille pattern blank (U+2800) [6]. This character is visually blank, but is
not considered to be a space or an ignorable code point.

Add ability to undelete accounts from within the console. Their password is reset, their name is
restored to their last known user name, and a mod action is logged.
Upload files in natural order rather than archive order when uploading archive files.
Before files were listed in the same order they appeared in the zip file. This could be in
non-alphabetical order, or even with files from different directories interleaved between each
other. Now files are uploaded in natural order, which is alphabetical order but with numbers sorted
properly, so that `file-9.jpg` appears before `file-10.jpg`.
A couple non-obvious consequences:
* Users can't flag non-rating:G posts in safe mode.
* Non-Gold users can flag Gold-only posts if they're the uploader.
* Add og:image:width, og:image:height, and og:image:type tags.
* Use og:video tags for videos.
* Use 720x720 instead of 150x150 preview images for videos.
* Add duration tag to JSON-LD data for videos.
* Add OpenGraph tags to media assets show page.
* Respect Twitter max image size limits.
* Don't include OpenGraph image tags when someone shares a plain https://danbooru.donmai.us link
with no tag search. This caused random potentially NSFW images to be shown when someone shared a
https://danbooru.donmai.us link on social media, which could be cached for long periods of time.
Fix bug where jobs had the opposite of the intended priority. Populating saved searches had the
highest priority, while processing uploads had the lowest priority.
Caused by Delayed::Job and GoodJob having opposite interpretations of job priorities. In
Delayed::Job, lower numbers had higher priority, while in GoodJob, higher numbers have higher
priority. This was missed when migrating from Delayed::Job to GoodJob.
* Fix exception in 65a17979c due to reference to `@media_asset` instead of `media_asset.
* Fix 05143dc9f not removing links to deleted images on the upload page.
On the upload page, change the file size info beneath the image to be formatted the same way as on
the media assets page, and to include a menu with links to offsite reverse image search tools.
Allow admins to delete media asset files.
This only deletes the image file itself, not the upload or media asset record. The upload will still
be in the user's upload list, but the image will be gone. The media asset page will still exist, but
it will only show the file's metadata, not the image itself. We don't delete the metadata so we have
a record of what the file's MD5 was and who uploaded it, to prevent the file from being uploaded
again and to take action against the user if necessary.
On the show page, add a icon beneath the image linking to the Danbooru post if the asset has been posted.
FIXME: Downstream boorus should change the icon to something else.
Show sources on the media asset show page. An asset can have more than one source if the same
file is uploaded from multiple sites.
Only sources from known sites are shown. Sources from unknown sites aren't shown because they
could potentially contain private information or identify the uploader in some way.
Known issue: Twitter posts often show two sources, the direct image URL and the page URL. This is
because someone uploaded the direct image URL first, and we're not able to tell that the image URL
and the page URL are for the same tweet.
Redesign the media assets show page to:
* Include sidebar with AI tags and image metadata.
* Include next and previous image buttons.
* Make the image use 100% of the available screen space and to scroll with the window.
* When a tag's category is changed, also change the category of any aliases pointing to it. For
example, if "ff7" is aliased to "final_fantasy_vii", and "final_fantasy_vii" is changed to a
copyright tag, then change the empty "ff7" tag to be a copyright tag too.
* Don't allow changing the category of an aliased tag. For example, if "ff7" is aliased to
"final_fantasy_vii", then don't allow changing the "ff7" tag to be a non-copyright tag.
This ensures that the categories of aliased tags stay in sync with that of their parent tags. This
way aliased tags are colored correctly in wikis and other places.
When regenerating thumbnails for a media asset, don't redistribute the original file. This is
unnecessary and also slow if it's a large file on remote storage.
Fix placeholder names like weibo_1234, bilibili_1234, nijie1234, and nicoseiga1234 being suggested
as Other Names when creating new artist entries. These are meant to be placeholders for the tag
name, not used as other names.
Hide the "Formatting help" link for single-line DText fields in dialog boxes, such as after the
"Reason" field in the flag, appeal, and report dialog boxes.
The `date:` metatag depends on the current user's time zone, so the post count for `date:` searches
needs to be cached separately for different users, otherwise it could lead to incorrect page counts
if two users with different time zones search for the same `date:` metatag at the same time.
