This is first quick port to QtWebEngine, most of advanced features
are not working yet. Please read README.
For now, it will use separate profile directory as well as browser
session, that means you can use both QtWebEngine and QtWebKit versions
at the same time.
Make sure the Configuration Information action won't be
detected as "Preferences..." action.
Also use native shortcut for fullscreen (Ctrl+Meta+F)
Closes#1332
Motivated by #695 which targets broader task, Ctrl-Q behaviour is one
that stands out. Accidentally pressing it instead of Ctrl-W can have
disasterous consequences or is annoying. Other browsers provide either
generic keyboard shortcuts configuration (Opera) or an extension/plugin
to disable the behaviour (FF).
For the record of the usability demand:

All actions are now saved in QHash with name, this will make possible
to implement own keyboard shortcuts for actions.
+ WIP cleanup of BrowserWindow class
