Make it easier for multiple people to admin a server
Please add some kind of admin list (for example data/admins.txt) that would contain client ids of server admins. Those players would be automatically granted master privileges when they join, so they would be able to execute master commands whitelisted by server owner. Currently logging in as master requires using a password, which means everyone who finds out what the password is can be a master. It's a bad idea for security reasons.
