****************************************************************************
* General *
****************************************************************************
- Important Changes:
* The enum value ResourceTypeUnknown has changed value because there was
a mismatch between 5.6 and 5.7+ definitions. In general any unknown
ResourceType value should be handled as unknown for forward
compatibility, because more types are and can be added in later
Qt versions.
- Chromium Snapshot:
* The Chromium version has been updated to 53.0.2785.148.
* Security fixes from Chromium up to version 54.0.2840.101
Including: CVE-2016-5181, CVE-2016-5182, CVE-2016-5183, CVE-2016-5185,

- General:
* Spellchecking support has been introduced.
* Build time options can now be controlled via arguments to the global
configure script or app.
* [QTBUG-52999] Added focusOnNavigationEnabled setting which allows
controlling whether a web view will receive focus on a navigation

* [QTBUG-54902] Added setting to allow secure content to run insecure
content.
* [QTBUG-54918] Printing will now include the CSS background of the
