Add transactions' input to getBlock RPC response

[thomasvds]

Currently when calling the web3.eth.getBlock() function, the array of transactions that is returned contains only partially correct information about the transactions.

Here is an example transaction retrieved with getBlock(58459):

{ 
    hash: '0xd11822009862abad1279da71eb1a869898a856df6c3325c7c2f6f3ac3a42c982',
    nonce: 20,
    blockHash: '0x0329ae704bb212b6b0de6c2cdac9251a012d70c06d86288554bb2d01e6b33458',
    blockNumber: 58459,
    transactionIndex: 0,
    from: '0xfd972bdA362588C1EDB81Bc22eF3E14E41e9aA60',
    to: '0x7A9C3d6373f11FC50969d7DA5A506623678C79d2',
    value: '0',
    gas: 0,
    gasPrice: '0',
    input: '0x' 
}

However I would have expected that the input field contains the actual transaction inputs (that is, the arguments passed when calling in this case a smart contract method).

This would prove very helpful to get much more details about transactions occurring in a given block, so as to be able to create rich block explorer functionalities.
