Server admins should be able to define a cooldown for any command.

This should be done by adding config options in the form :

• Commands.<command>.cooldown

Cooldowns should be in seconds. Alternatives formats (Xs, YmXs, ZhYmXs) might be considered but could cause parsing issues.

• Cooldowns should be managed at player level. Only the player that triggered a cooldown should be prevented from using the command for the given period.

• Cooldowns should be displayed in the command usage when a player execute /zh help command.
