Analyzer Zoom-In and Zoom-Out disable/enable
Analyzer Zoom-In and Zoom-Out disable/enable

The Zoom-In and Zoom-Out options in the view menu of the analyzer are
now disabled when the option is not available. This in done in a new
setZoom method in the TestFrame class which manages zoom logic at
the frame level.
