Add CheckDelegate

CheckDelegate is an item delegate that is used in lists, and can be
checked and unchecked. It derives from QQuickItemDelegate and hence has
background press effects. The order of the indicator and text is
reversed (compared to CheckBox) to reflect what is most commonly seen
on mobile.
