Title: Fixed bug with own deserialization routine and added possibility to specify own serialization routine for non-value types

Concerning the bug:

If you configure only JsConfig.DeSerializeFn without configuring JsConfig.SerializeFn, it will not be used during deserialization.

Concerning the change:

As far as I checked code and tested it with few types like CultureInfo, checking if JsConfig.SerializeFn is enough for using it, deserialization works fine without any changes.
