Combine the zoom menu entries into one Line

Replaced a KActionMenu that contained separate Zoom In, Zoom Out and
Reset Zoom actions with a single QWidgetAction that provides the same
functionality using three buttons arranged in a single line. Keyboard
shortcuts for the three actions are preserved, and the actions still
appear separately in the View submenu in the menubar.
