Allow `uuid` shorthand and automatic primary key

[jasonmccreary]

While uuid column types are support, they are currently a bit verbose to define.

It would be nice instead of the current definition of id: uuid primary, to be able to simply use a shorthand of uuid that would expand to id: uuid

This implies the use of the primary modifier if a user were to define id: uuid.

I think @ttomdewit mentioned taking a stab at this. If not, I'll work on it during the next live-stream.

I was hoping to do it last night but unfortunately had to finish some other work. Can’t see myself finishing it within the next 8 hours or so before your livestream but if I do I’ll make sure to ping you.
