Default zoom level should match OS setting

[D1G1TE]

Issue can be observed on HIDPI systems, like 15 inch laptops with 4K display. Default OS zoom level is 200%. But Liri is rendering pages with 100% by default, regardless OS wide settings. Tested on Windows 10 latest Insider preview.

Hey @D1G1TE, thanks for reporting. This is most probably an upstream bug in Qt/QtWebEngine. We need to check if it was fixed with Qt 5.6's new High-DPI-Support.
