    Improving GcalView API.
    
    Added GcalView::update signal for when the view will change it's date range
    Added GcalView::create-event signal for when the view wants to create a new
    event
    
    Added GcalView::clear_selection method for clearing new-event mark.
    
    Note: The views can choose to mark before send a ::create-event signal the range
    over which they will create the new event. This will be called new-event mark.
