Summary:
I couldn't resist to do this 😄#394
This adds ```flex-wrap: wrap-reverse```
I think we hit a edge case here:
https://stackoverflow.com/questions/33891709/when-flexbox-items-wrap-in-column-mode-container-does-not-grow-its-width
as is differs here from chrome, but I think that yoga is here more correct.
So I haven't added this test yet as this would fail against chrome, as chrome outputs a width of 30 for root, whereas yoga gets a width of 60 here, which I think is correct. Strangely the output of ```flex-wrap:wrap``` is in jsfiddle also only with a (visual) width of 30 on chrome, while the tests gets generated with 60.
```html
<div id="wrap_reverse_column" style="height: 100px; flex-wrap: wrap-reverse">
<div style="height: 30px; width: 30px;"></div>
<div style="height: 30px; width: 30px;"></div>
<div style="height: 30px; width: 30px;"></div>
<div style="height: 30px; width: 30px;"></div>
</div>
```
Looking forward what you think here emilsjolander
