title: How to disable swiping to other tab inside nested StackNavigator
body: <p>I have little problem... I have StackNavigator nested inside TabNavigator, something like:</p>
  
  <ul>
  <li>Tab1
  
  <ul>
  <li>Stack screen</li>
  </ul></li>
  <li>Tab2</li>
  <li>Tab3</li>
  <li>Tab4</li>
  </ul>
  
  <p>I want to preserve swiping while on tabs view but want to disable it when I open StackNavigator. I have tried applying "swipeEnabled: false" on navigationOptions of StackNavigator but it cause some wierd behavior (disabled StackNavigator show animation and rerendered view inside tabNavigation when I went back). Anyone have Idea how to achive that?</p>
