Internalize JSON.NET dependency

[davidfowl]

Today we're using JSON.NET as a package and that's no good for apps and frameworks that use this framework. This is part of the work #29

Just talked to @Eilon and we might want to use DataContractJsonSerializer instead of a new parser written by us. Need further discussion and mark this as blocked.

Ummmmmmmmmmmmmm.

[Eilon]

No ummmmmmmmmming just yet! Specifically, we should consider using DataContractJsonSerializer, if it supports what we need. I don't think it's in CoreCLR yet, but it will be (according to what I've heard). But if it doesn't support what we want (e.g. comments), then we're off to the races.

That serializer is terrible 😄

Just copy and paste JsonReader + JsonTextReader out of Json.NET, then write some code to load the JSON into a simple Dictionary/List/value object model.

Example of loading JSON into a simple object model using JsonReader: https://github.com/JamesNK/Newtonsoft.Json/blob/bcd6982419c6165ed2c606eb9994c1aa6bce3735/Src/Newtonsoft.Json/Converters/ExpandoObjectConverter.cs#L62-L138

We should close the following issues after this is done:
