* permission `.` grants dotfile visibility if user has `r` too
* `-ed` will grant dotfiles to all `r` accounts (same as before)
* volflag `dots` likewise
also drops compatibility for pre-0.12.0 `-v` syntax
(`-v .::red` will no longer translate to `-v .::r,ed`)
* start banning malicious clients according to --ban-422
* reply with a blank 500 to stop firefox from retrying like 20 times
* allow Cc's in a few specific URL params (filenames, dirnames)
not even the deprecationwarning that got silently generated burning
20~30% of all CPU-time without actually displaying it anywhere, nice
python 3.12.0 is now only 5% slower than 3.11.6
also fixes some other, less-performance-fatal deprecations
* --ban-url: URLs which 404 and also match --sus-urls (bot-scan)
* --ban-403: trying to access volumes that dont exist or require auth
* --ban-422: invalid POST messages, fuzzing and such
* --nonsus-urls: regex of 404s which shouldn't trigger --ban-404
in may situations it makes sense to handle this logic inside copyparty,
since stuff like cloudflare and running copyparty on another physical
box than the nginx frontend is on becomes fairly clunky
* --doctitle defines most titles, prefixed with "--name: " by default
* the file browser is only prefixed with the --name itself
* --nth ("no-title-hostname") removes it
* also removed by --nih ("no-info-hostname")
