Props not passed into connect selector about react-redux

[hartzis]

@TimothyKrell, it looks like in v0.5.0 you now have access to the components parent props via the third argument passed to connect

https://github.com/gaearon/react-redux/blob/master/README.md#connectmapstatetoprops-mapdispatchtoprops-mergeprops

Example from readme:

Inject todos of a specific user depending on props, and inject props.userId into the action

import * as actionCreators from './actionCreators';

function mapStateToProps(state) {
  return { todos: state.todos };
}

function mergeProps(stateProps, dispatchProps, parentProps) {
  return Object.assign({}, parentProps, {
    todos: stateProps.todos[parentProps.userId],
    addTodo: (text) => dispatchProps.addTodo(parentProps.userId, text)
  });
}

export default connect(mapStateToProps, actionCreators, mergeProps)(TodoApp);

Thanks! Should have read the README more carefully. Sorry for the noise!

Yeah, this was done because once you want to something with state by props, you'll likely want to do something with actions too, but we can't rebind actions on every prop change (wasteful!) if you don't care about props. Hence the third argument.
