BREAKING

Example response:

```json
{
  "jsonrpc": "2.0",
  "id": "",
  "result": {
    "height": "2109",
    "txs_results": null,
    "begin_block_events": null,
    "end_block_events": null,
    "validator_updates": null,
    "consensus_param_updates": null
  }
}
```

Old result consisted of ABCIResponses struct and height. Exposing
internal ABCI structures (which we store in state package) in RPC seems
bad to me for the following reasons:

1) high risk of breaking the API when somebody changes internal structs
(HAPPENED HERE!)
2) RPC is aware of ABCI, which I'm not sure we want
