Referral Contests 2 by Siropu 2.3.3

Fixed an issue with potential referral link decoding error when invalid ID is provided.

Added a new option called "Enable referrer auto-follow referral" where referrer will auto-follow the referral upon registration.

Made some changes to the referral link where it is now displayed in an input field with a copy to clipboard function, for a more compact look.

Fixed an issue with the "Encrypt user ID" feature where the hashids script used is no longer compatible with PHP 8.2 or newer and it has been replaced with sqids. If you have been using this feature and running at least PHP 8.1, you have to ask your users to update their referral links because they have different IDs now.

Fixed a potential error on user registration with invalid IPs.

This version is compatible with XF 2.3 only.

Updated to latest version the Hashids script used for generating unique IDs from user id when "Encrypt user ID" admin option is enabled.

Fixed an issue with share links where referral links can result in 404 not found.

Added "top referrers" widget option to display top referrers from certain contests.
Added IP in referrals list in ACP linked to the list of users that might have used the same IP.

Fixed a potential error with referrer custom field.

The code has been cleaned up and important parts have been moved from the Listener to Entity and Repository.
