Title: Fixed bug with setting a style property to a unknown value in IE8 and lower

IE8 and lower throws an error if you try to set a style property to an unknown or invalid value. Can be tested with these two lines:

```javascript
var element = document.createElement('div');
element.style.backgroundRepeat = 'round';
```
