Title: window.open(url, '_system') does work now

Checking the variable `featString` for null value.
If third parameter of `window.open()` is not used, the method fails at `featString.Split(',')` because featString is null.
This was the reason why `window.open()` with target `_system` did not work on Windows Phone.
