server AR cooldown#138

this relates to the {cooldown:00} variable. i was thinking we could have a server cooldown, where it’d basically affect every user in the server.

imagine, i as a single person trigger a ar with the {cooldown:60} variable. now, i can only use the ar after 60 seconds BUT that only applies to me. i would want a {server_cooldown:60} so every member in the server would have the same cooldown for that specific command.
i believe it would be useful for certain things like daily/weekly free currency.
