[Xen-Soluce] Required Custom Fields On Upgrade 2.1.0

Great addon ! Needed to have some custom fields required before allowing a user to use the account ugprades so it works as expected.

Merci Xen-Soluce !

This Add-on is great and you made it more usable in the latest update, admin can force users to fill some fields before upgrade their account. The developer are listening to the customers and developing this add-on in short time. Thanks and keep it up.
