The example provides styling for the tab icon via the `icon` property in the styles object. However in the example, it is used as `tabIcon` which does not exist.

When the drawer opens / close, the result of AppNavigator.router.getStateForAction(action, state); is null. So the nav state in the store is null which causes errors. This solves that.
Per request [#228](https://github.com/react-community/react-navigation/issues/228), I've updated the the Hello Mobile Navigation guide to try and make it more approachable to newcomers like myself. I changed the order of some of the explanations and broke out passing params into its own section. This should make the guide easier to follow as only one new concept is introduced per section; a common principle in teaching methodology.
I'm open to suggestions as I am also a newcomer to both React Native and React Navigation. So it's very possible that there are concepts that I've misunderstood or am not explaining well.
