#3026:

• deleted: ConvertableAttribute, DummyConverter, ObjectExtensions
• renamed: CustomJsonWriter -> SingleLineArrayJsonWriter, JCInstantiator -> JsonTemplateInstantiator
• added: JsonItemConverterFactory, UnsupportedJsonItem
• IJsonItemConverter:
  • added two new properties: Priority and ConvertableType -> because converters are automatically collected by plugin infrastructure now
  • Extract, Inject references a root converter now -> typically an instance of JsonItemConverter -> to prevent cycles
• JsonItemConverter:
  • now implements the interface IJsonItemConverter
  • is now a dynamic class
  • is only instantiable with an factory (JsonItemConverterFactory)
  • still has the old (but now public) static methods Extract and Inject (without ref param IJsonItemConverter root) -> creates instance with factory and calls methods of instance
  • removed register and unregister methods, because the factory collects all converters automatically now (on first call of Create)
  • has cycle detection for Extract and Inject
  • renamed method Get to GetConverter
