Improve whitelist system

[Kapppa]

• Syncs the Servers whitelist to the client.
• Clients have still have their own whitelist.
• Auto loading of whitelist on the server. (I can add the ability on client if needed)

I'm not so sure what this does still, does it sync the serverside whitelist to the client if its custom and the client doesn't have a custom one?

Thanks for the PR

If the server loads the custom whitelist, it sends that whitelist to the client as well. But some people still may want to have a custom whitelist on their client. So I made the client whitelist separate from the server one. So if a client loads their whitelist, it will take priority over the server one.

Made some fixes & pushed to workshop. Thanks
