Make hoverEnabled propagate to children

Hover effects can be sometimes a bit disturbing. This change makes it
possible to conveniently disable hover effects for a tree of controls
in one go. For example, to disable hover effects for a page including
its header, footer, and all list items:

    Page {
        hoverEnabled: false
        header: ...
        footer: ...
        ListView {
            delegate: ...
        }
    }

[ChangeLog][Controls][Important Behavior Changes] Control::hoverEnabled
has been made to inherit to children, to make it possible to disable
hover effects for a tree of controls in one place.
