Emil Sjolander cc275557be Add margin auto support to react native ...

Summary:
This diff adds margin:auto (https://drafts.csswg.org/css-flexbox-1/#auto-margins) support to React Native. This enables layout not previously supported without inserting empty 'spacer' views. See below Playground for usage.

```
class Playground extends React.Component {
  render() {
    return (
      <View style={{width: '100%', height: '100%', flexDirection: 'row', backgroundColor: 'white'}}>
        <View style={{width: 100, height: 100, backgroundColor: 'red'}}/>
        <View style={{width: 100, height: 100, marginLeft: 'auto', backgroundColor: 'blue'}}/>
      </View>
    );
  }
}
```
