Ability to partial update an object #2

A partial update for a document so that can be used with the PATCH request. It is also more bandwidth friendly if MongoDB is hosted externally.

Shouldn't be difficult to implement. MongoDB has the $set operator which perfectly aligns with this.

I already implemented this last week. I'll update the docs soon, but in short: Meow generates a Values struct that represents partial values of a model. Currently you can myModel.update(with: partialValues.serialize()) but this will be more seamless in the future.

You can see how I handle PATCH requests in MeowVapor here: https://github.com/OpenKitten/MeowVapor/blob/master/Sources/MeowVapor/ModelController.swift#L64
