Have JSONValue conform to JSONDecodable

[gfontenot]

If JSONValue conforms to JSONDecodable, we can cut the number of operators we define in half in favor of using chained parsing operators.

j <| ["foo", "bar"] would become j <| "foo" <| "bar"

This would also allow us to get rid of subscript, as well as find probably.

There might be performance implications here.

Thumbs up. The subscript thing is not even intuitive.
