Discord API - Scheduled Guild Events

[maxcell]

Back in October, Discord released a new feature called Scheduled Guild events that allows guilds to schedule meetings so members can gather together, online and offline! As a fast follow they released documentation over that API. It would be great to implement these into serenity (and I'd be happy to take the time to implement them if I can receive feedback around my modeling as it comes)

Primarily it looks like there are about 6 APIs they offer:

1. List Scheduled Events for Guild
2. Create Guild Scheduled Event
3. Get Guild Scheduled Event
4. Modify Guild Scheduled Event
5. Delete Guild Scheduled Event
6. Get Guild Scheduled Event Users

I am not certain exactly what modeling we'd need to do but nothing feels too spicy. We'd definitely need to add more models but I don't think there are any extending of existing models (e.g. users) we'd have to do.
