Subject: [PATCH] Optimize whitelist command for multiple additions / removals
Previously the whitelist command was adding players 1 by 1. This caused massive overload
when you were adding multiple players due to the fact it saves every time a player was
added.
These changes aim to reduce that load whenever you are using the /whitelist command.
