Title: avoid null error on dispose when view has no subviews

I'm getting a bug when I try to dispose of a view without any subviews.

```
_ref = this.subviews
for (_i = 0, _len = _ref.length; _i < _len; _i++) {
...
}
```

This is a standard coffeescript `for subview in @subviews` loop, but it fails when @subviews is undefined
