Add whitelist changes to console log

[Cooldude2606]

Currently ban/unban/promote/demote all have actions within the console log however changes to the whitelist do not. This makes it more challenging to sync changes to the whitelist between servers. My current process used for ban syncing is: tail console log -> see [BAN] or [UNBANNED] -> send rcon /ban or /unban to all other servers -> have logic to prevent infinite loops. The same process works for promote/demote. This is not possible for whitelist. An alternative would be a new event, but this would impact game state. Therefore I would like to see whitelist changes have actions in the console log.
