Added preventDefaultAction flag to MouseTracker
Added a boolean preventDefaultAction property (default false) to the event object passed to MouseTracker handler methods. Implemented in the following MouseTracker subscribers: * Viewer.keyboardCommandArea.innerTracker.focusHandler: preventDefaultAction == true prevents scrolling viewer into view * Viewer.keyboardCommandArea.innerTracker.keyHandler: preventDefaultAction == true prevents viewer keyboard navigation * Viewer.innerTracker.clickHandler: preventDefaultAction == true prevents viewer zoom on click * Viewer.innerTracker.dragHandler: preventDefaultAction == true prevents viewer panning with mouse/touch * Viewer.innerTracker.scrollHandler: preventDefaultAction == true prevents viewer zooming on mousewheel/pinch
