* template-based title formatting
* picture embeds are no longer ant-sized
* `--og-color` sets accent color; default #333
* `--og-s-title` forces default title, ignoring e2t
* add a music indicator to song titles because discord doesn't
plus misc similar technically-incorrect addq usages;
most of these don't matter in practice since they'll
never get a url with a hash, but makes the intent clear
and make sure hashes never get passed around
like they're part of a dirkey, harmless as it is
when switching to another folder with identical filenames, the
mediaplayer would get confused and think it was the same files,
messing up the playback order
to abort an upload, refresh the page and access the unpost tab,
which now includes unfinished uploads (sorted before completed ones)
can be configured through u2abort (global or volflag);
by default it requires both the IP and account to match

as this option is very rarely useful, add global-option `--k304` to
unhide the button and/or set it default-enabled
the toggle will still appear when the feature was previously enabled by
a client, and the feature is still default-enabled for all IE clients
if a reverse-proxy starts hijacking requests and replying with HTML,
don't panic when it fails to decode as a handshake json
fix this for most other json-expecting gizmos too,
and take the opportunity to cleanup some text formatting
* docker: warn if there are config-files in ~/.config/copyparty
because somebody copied their config into
/cfg/copyparty instead of /cfg as intended
* docker: warn if there are no config-files in an included directory
* make misconfigured reverse-proxies more obvious
* explain cors rejections in server log
* indicate cors rejection in error toast
`@import url(https://...)` would get rewritten to baseURL + https://...
also reorder the generated csstext so that @imports appear first;
necessary for stuff like googlefonts to take effect
some reverse-proxies expect plaintext replies, and
we don't have a brotli decompressor to satisfy this
additionally, because brotli is https-gated (thx google),
it was already an impractical mess anyways
the sfx is now 7 KiB larger
chrome crashes if there's more than 2000 unique SVGs on one page, so
there was serverside useragent-sniffing to determine if the icon should
be an svg or a raster
however since the useragent is not in our vary, cloudflare wouldn't see
the difference and cache everything equally, meaning most folders would
display a random mix of png and svg thumbnails
move browser detection to the clientside to ensure unique URLs
