Added new check: NicknameCheck - it uses regular expressions (regex) to validate nicknames.
Added new command: /guard analyze - you can provide an IP address or nickname, and it will show you details about the user, such as country, city, blacklist/whitelist status, and alt accounts.
Added nickname whitelist and blacklist. Commands /guard whitelist add/remove and /guard blacklist add/remove now also accept nicknames. Check your message.yml file if you translated these commands before.
Fixed many issues with AccountLimitCheck, such as not being able to login with any account after reaching the limit (may still be unstable).
Added metrics for Velocity version.
Many minor improvements in the code.
Example of /guard analyze City and country are unknown because this is a localhost address.
