Navigator config to pass params down

I was chatting with @geirman and I think we may want to add passParams to the navigator config:

createStackNavigator({
  Main,
  MyTabs: createTabNavigator({
    A,
    B,
  }, { passParams: [ 'foo' ] })
})

Say you go from Main .navigate('MyTabs', {foo: 'bar'}).. Thanks to the proposed passParams, screens A and B would have access to the "foo" param.

I'll try to get to this in the coming weeks. Let me know if anybody wants to take a stab at implementing this.. I'd be happy to support you.

For more info (if needed), this came about because I needed to pass params down from a tab navigator to a child stack navigator. Here's a link to the stack overflow, which has a link to a snack demo. Thanks for the work around, @ericvicenti !
