Webbrowser example: Fix crash due to deprecated code.

The example uses a Qt Designer form with widgets on a QToolBar
imported from Qt 3 which is not supported in Qt 4 and later.

In the code generated by uic, a QLabel is constructed passing
the toolbar as parent and added to the toolbar using
QToolBar::addWidget() which then causes a crash in Qt 4.

Move the widgets from the form into the class to avoid this.

Task-number: QTBUG-36948
