Minor code tweaks, nothing real notable. Jar no longer includes 0-byte config.yml because that's kinda weird. api-version has also been changed to 1.13 so it should run on servers between 1.13 and 1.16 as well now. Server versions other than the latest are not a priority, however.

The part that follows is just for testing, BungeeServerName supports all versions as far as I'm aware, including versions such as 1.14.4 and 1.15.2. So just ignore this:
Supported versions: 1.8.8, 1.12.2, 1.16.5, 1.17.1, 1.18.2
