Binoculars: Update to use 'zoom_fov' player property
In survival mode, zoom is disabled, the binoculars item is needed to allow a zoom with a 10 degree FOV, realistic for compact binoculars. Creative mode or per-player creative privilege allows a zoom with a 15 degree field of view (the default MT engine zoom FOV).
