Ignore content in json when bracket when remove padding

For some case, the jsonp data can have a bracket ")" in quotes, like:

``` json
callback("key","I'm so happy:)")
```

But the remove padding use `tokenQueue.chompBalanced('(', ')');` in Jsoup, so the result will be "("key","I'm so happy:".

I will add a method `chompBalancedNotInQuotes` in Xsoup and fix it.
