get the execution result in ethGetTransactionReceipt

[adridadou]

I am currently working on eth-contract-lib. This is a java library to interact with smart contracts.

I've implemented a first backend with EthereumJ and I would like to be able to use RPC as well. This way, it is possible to create applications that don't need to sync to work and can even be used on mobile.

One of the feature I have already implemented for the EthereumJ version is to get the returned value from a sendTx function call.

In EthereumJ, you have access to the executionResult in the transaction receipt that can be decoded and converted into a returned value(s).

It would be great to have the same functionality in the RPC API.

@adridadou this is also being (partially?) addressed by #1.
