Updated all newtonsoft.json versions to 6.0.3.
Updated TestClient rx-main version to 1.0.11226 - now on par with AustinHarris.JsonRpc.Client.
Removed hard-linked Newtonsoft.Json.dll from the root folder - we should be just using nuget package now.
Removed hard-linked System.Reactive.dll from root folder - we should be just using nuget package now.
Fixed solution file - TestServer.csproj should load all good now.
