Feature Request: Make spam rate limiting configurable

[evidex]

Would be awesome to be able to configure spam rate limits via config.py, particularly allowing "vip" users to exceed spam limits.

Spam limits are set by Discord API these are unchangeable.

He's referring to the rate limiter I built into the bot. https://github.com/shibdib/Firetail/blob/master/firetail/core/checks.py#L25

I can look into making this customizable.
