Subject: ev-view: Add pinch/zoom gesture to handle document zooming

This is delegated on a GtkGestureZoom. When triggered, the document
will be zoomed based on the distance changes between both fingers.
When the gesture is not active, regular event handling (text selection,
clicking, etc...) will happen.
