Group membership moderators 2.3.0

• Require XenForo 2.3+.
• Require PHP 8.0+.
• Require Standard Library v1.21.0+.
• Add password-based confirmation when adding / removing users from a group.
• Minor code clean up.

• Only show 'Group Moderators' menu item if the user is a group moderator
• Added multi column layout in ACP for the list of groups

• In some situations the user was not removed properly from a group. This has been fixed.
• Rewrite of add/remove function

• This add-on now uses the Standard Library add-on from Xon. Make sure to install this as it is a requirement.
  We were already using this library, but now it is an official add-on which makes library updates much easier.
• Confirmed compatibility with XF 2.2!

• Removed redundant files in archive (src/addons/SV/Utils/.git/*)

This add-on can now be downloaded and used for free. No branding! Have fun ...

• Fixed problems with "Group based" moderators after security hotfix
• Minor code cleanup

• Bugfix: some group properties where not added correctly (thanks @Vanjoe for the report)
• Improved add/remove user group function
• Actions are now also logged in user change log

• Actions are now also logged to the moderator log

Note: This will only work if the user is a moderator (this is by Xenforo design). If you also want to log actions from non-moderators you will need this extra add-on: Log all moderator actions

Warning: Always make a backup and test before installing this on a production forum.

• New feature: It is now possible to assign a group of members as 'group moderators'
• Bugfix: Creating a new group and adding a group moderator at the same time would result in an error.
• Bugfix: Better cleanup when removing a group with group moderators assigned. This would result in some problems.
