Explicit false player permissions

Some commands are available to everyone by default, even if they are not an operator.

For example, the /plugins command is available to everyone by default on Bukkit servers, but you might not want this.

To explicitly block a command, use:

/lp user <player> permission set <permission> false

For example, to block Minecraft123 from using /plugins, you can use:

/lp user Minecraft123 permission set minecraft.command.plugins false
