getaddednodeinfo should return an array #2467

When getaddednodeinfo is called with dns=false it returns something like this: {"result":{"addednode":"faucet.bitcoin.st","addednode":"faucet.bitxcoin.st"},"error":null,"id":null}

I expected restult to be an array, and when calling with dns=true that is also what I get. Isn't it supposed to always return an array?

I'm trying to deserialize this in Java, and that would be much easier if it always returned an array.

Would probably have been easier if this had been done when designing the API. However at this point, changing the interface is going to cause more trouble than it solves.
