v3.3.1 Updates and Patches

Updates:
- Severity Aliases. You may now add aliases to severities. After setting an alias, you may directly use it as a value. You may configure this in the severities GUI.
Ex. /ban username alias reason (/ban Coralise xray Xraying.)
- Banlist. Added /banlist command. You need the "custombansplus.ban" permission to access it.
- New permission: custombansplus.login.notify.banned. Players with this permission will be notified when a player joins the server with banned alts.

Patches:
- Patched first time join bug. The plugin did not store player data properly upon their first login to the server. This is now fixed.
- Fixed Perm Bans not being stored properly at times.

IMPORTANT NOTE: If you have the previous version (v3.3.0) installed, you must update the players and active_bans table of your MySql/SQLite database from NOT NULL to NULL or NULLABLE.
