Changing pointer cursor in examples is broken

As reported on the [mailing list](https://groups.google.com/d/msg/ol3-dev/2E7I5dQPls0/XvluAXizpMAJ) changing the pointer cursor with

```js
map.getTarget().style.cursor = 'select'
```

as done in the icon example, no longer works. Commit d3b2b1cd9e3d446c2cf4f75f205b16c436d45fb8 (the changes to the CSS file) broke it.

@austinhyde, any idea on how to fix that?
