Remove hard Json.Net version dependency

[mrchief]

Json.Net is at 5.0 now but Spring.Rest (Json.NET support) has a hardcore dependency on v4.5.10.

You can either embed (ilmerge) Json.Net or remove the specific version dependency so that people are not forced to downgrade Json.Net.

Spring REST never had hard dependency on JSON.NET as you can see in the NuGet page:
http://nuget.org/packages/Spring.Rest/

JSON.NET is supported by using a custom converter that you can get with separated package named Spring.Http.Converters.NJson :
http://nuget.org/packages/Spring.Http.Converters.NJson/
http://www.springframework.net/rest/refdoc/http-messageconversion.html#http-njsonconverter

Maybe we should rename the NuGet package "Spring.Rest (Json.NET support)" with "Json.NET support for Spring.Rest" to avoid confusion.

I didn't say just Spring.Rest now, did I? The name is a odd one but the issue still remains: http://nuget.org/packages/Spring.Http.Converters.NJson/ has a hard dependency on a specific version of JSON.Net.

Reference for Json.Net is still hard.
Why reliase 1.1.2 not in nuget.org?
