Subject: - Choose the correct MainView in ZoomBar::updateSlider()   It fixes
 issue for the first tab of new windows in case of a "wheel" zoom. - Move the
 zoom bounding logic from WebView::wheelEvent() to ZoomBar::setValue()   It'll
 avoid Ctrl -/+ to exceed the max value of the slider - Use the round() method
 instead of my previous hack to compute zoom ratio for wheel events
