Use nativeEvent argument in onLayout instead of container.measure

[newtonry]

this.container.measure was not returning the full height and width if the screen was in the middle of a transition. This caused a miscalculation where the full container view was not taken up. Example:

onLayout (http://facebook.github.io/react-native/releases/0.45/docs/view.html#onlayout) receives the same view's dimensions with event.nativeEvent.layout. The docs suggest using those instead
(http://facebook.github.io/react-native/releases/0.45/docs/direct-manipulation.html#measure-callback).

This change sets the correct width and height and gives the expected behavior instead:

@phil-r was there any reason for using the container.mesure function? this fix looks good to me, @newtonry nice finding!

+1 is this repo alive?

[newtonry]

@i8wu it doesn't seem to be too active. It appears that https://github.com/archriss/react-native-snap-carousel finally added a much wanted loop feature. That's a much more active library, so I might switch over soon.

Thanks for the heads up @newtonry , will check out the other module as well.
