Move common.pri to the root directory to be able to use it with tests.
Remove nano browser specific logic (util.h include and common resources)
from this file and use relative paths in the examples instead.

This also remove unnecessary directives:
- lib doesn't have to be added to INCLUDEPATH since proper modules are used
- util.h doesn't need to be added to HEADERS, moc doesn't need to go through it
- MOC_DIR doesn't have to be adjusted anymore

- Remove the dashes from the target names
- Rename the qtquick example directory to quick, matching the style in lib

This is the first step to making proper Qt Modules out of QtWebEngine.
The Widgets integration becomes a proper C++ Qt Module while we make
the QtQuick side a QML plugin for now (could probably be promoted if
the need arises).

Code-wise, this means the introduction of a WebContentsAdapterClient
interface that is subclassed by the private implementation of our API
classes for delegation of things that are UI specific. Functionality
from WebContents and the like is exposed via the WebContentsAdapter.

Use the same icons for the widgets and qtquick example.
Remove the styling as it does not work on all platforms anyway.
