* Rename Upload#download_for_upload to #get_file_for_upload.
* Fix #get_file_for_upload to raise error if no file or source url was given.
* Fix javascript upload validation to disallow submitting form if file is
not present and the source is not an url.
Bug: in the modqueue, if a user does a detailed rejection of one post,
then tries to do a detailed rejection of another post, the form will
still be filled in with the rejection message from the previous post.
Bug: if you open the tag edit dialog with shift+e, close it, then open
it again, it won't be vertically centered when it opens the second time.
Fix: hide the related tags section *before* opening the dialog, not after.
Hiding it afterwards shifts the layout, which uncenters the dialog.
Initialize the recent tags, frequent tags, translated tags, and artist
tags columns only once, when the related tags section is first shown.
The related tags section is shown automatically when the 'Edit' tab is
opened, or by default on the uploads page.
This fixes the /related_tags.js and /source.js calls being triggered
every time the tag edit dialog box or the 'Edit' tab was opened.
Refactor the /related_tags.js call so that when the "Related tags"
button is clicked, it only replaces the columns that actually changed,
not the entire related tags section.
This avoids rebuilding the Recent / Frequent / Translated Tags / Artist
columns every time the "Related tags" button is clicked.

Bug: `Cookie.get("news-ticker") === key` always returned false because
the cookie was a string but the key was an integer.
Regressed in f72b32b27b after switching from `==` to `===`.
Drop support for the following pseudo-metatags in the Name field in the
artists search form:
* name:<name>
* other:<other name>
* group:<group name>
* status:banned
* status:active
* http://www.example.com
Instead, make the Name field do a wildcard search against the artist
name, group name, or other names. If the query looks like `/regex/`,
then do a regex search against any of these names.
/artists?search[name] now does a literal exact match and
/artists?search{any_name_matches] does the above wildcard/regex search.
* On posts, automatically trigger "Fetch source data" when clicking the
Edit tab, instead of triggering the artist finder button. This way we
find both the artist and the translated tags in one ajax call.
* Remove the "Artist" finder button next to the source field. This isn't
necessary given that "Fetch source data" finds the artist itself.
* Remove the /artists/finder.json API endpoint. This is no longer used
after removing the "Artist" finder button.
Instead of calling /sources.json and rendering the "Fetch source data"
box client-side in Javascript, call /sources.js so we can render the
html server-side.
Captioned post previews (previews with the pool name, similarity, or
size beneath) need to have `height: auto` set, otherwise they'll default
to `height: 154px` (just enough for the image) and the caption won't be visible.
