Add RunInNTicks or RunOnTick

[busheezy]

It would be great to be able to do things like "run in 3 ticks."

RunInNTicks(3, () => Logger.LogInformation("wooo, 3 ticks!"));

and/or

var futureTick = Server.TickedTime + 3;
RunOnTick(futureTick, () => Logger.LogInformation("wooo, 3 ticks!"));

This has been discussed briefly here: #354 (comment)

Killstreak made something for this a while ago, don't know if it still works or not.

Yep, it's mentioned in the comment linked above.

I was going to bring an issue up sooner or later about integrating it into CS#, it's nice.
