Feature: Add support for InstanceCreatorEx interface with createInstance(JsonElement json, Type typeOfT)

[GoogleCodeExporter]

json data can contain information about which exact class should be created,
but original InstanceCreator can't use this information.

Example: 
I have abstract Command class and Command1, Command2, etc subclasses.
My json data contains "type":"Command1" pair.

So we can overcome "Collections Limitations" and can deserialize 

Collection[? extends Command] realCommands = gson.fromJson(json, 
collectionTypeCommand);
