Support for relative URLs.

I'm using wkhtmltopdf tool to fetch remote html files which uses Qt/QtWebKit, however it seems there is a problem with relative URLs.

Here are few samples:

<script src="//cdnjs.cloudflare.com/ajax/libs/numeral.js/1.4.5/numeral.min.js"></script>
<script src="//cdn.optimizely.com/js/653710485.js">
<script src="//pagead2.googlesyndication.com/pagead/js/google_top_exp.js">
<img src="/images/filetypes/txt.png">

All requests to those files are ending up with: QNetworkReply::ContentNotFoundError error.

Is it something that can be fixed?

Version 0.11.0 rc1 did not not have this problem as suggested here: https://github.com/wkhtmltopdf/wkhtmltopdf/issues/2359#issuecomment-108773404.
