This commit introduces a new feature where users can disable the collection and display of IP addresses. It's hardcoded in the .env config file for security reasons, and demo mode ignores this setting, because it already hides IPs by default.
This commit adds a password strength requirement for new users using
regular expressions.
Also adds a dismissable alert so users know how to create passwords
properly.
This commit makes optional registration parameters optional; They should only be filled in after the user has submitted an application. The application will crash during registration without these parameters being optional, and adding them to the form would be illogical.
