4.20.7

* Changed: Start fetching FFZ badges based on user ID rather than user login, for both data savings and resilience against name changes.
* Changed: Implement a hot path for the Supporter badge (which is now applied to over 20,000 users) to reduce resource usage, notably RAM.
* API Changed: Update to a newer method of getting an APIv2 authentication token that doesn't require a socket server connection.
