🧪 new features

hooks now behave more usefully/predictably; 889bd32
- hooks returning 0 will run the next hook (if any), and let the initiating action proceed if no other hooks object
- hooks returning 100 will stop processing successive hooks, but return success, letting the initiating action proceed
- hooks returning anything else will stop processing successive hooks (like the documentation always said) and also fail the initiating action (if hook is checked)
- zmq hooks can now respond with json, doing relocations and all that stuff

also... it's december! you know what that means :^)

download link	is it good?	description
copyparty-sfx.py	✅ the best 👍	runs anywhere! only needs python
copyparty-en.py	✅ also good	same but english-only, no i18n
a docker image	it's ok	good if you prefer docker 🐋
copyparty.exe	⚠️ acceptable	for win8 or later; built-in thumbnailer
u2c.exe	⚠️ acceptable	CLI uploader as a win7+ exe (video)
copyparty.pyz	⚠️ acceptable	similar to the regular sfx, mostly worse
copyparty-en.pyz	⚠️ acceptable	english-only, no smb-server
copyparty32.exe	⛔️ dangerous	for win7 -- never expose to the internet!
cpp-winpe64.exe	⛔️ dangerous	runs on 64bit WinPE, otherwise useless
bootable usb	┐(ﾟ∀ﾟ)┌	a surprisingly useful joke (x86_64)
