Add current GF to infobox
As per request from users on scubaforum.com, this adds the current gradient factor to the deco information of the infobox. Up to now, this information was only graphically represented in the pressure bar graph and the heatmap. This gives a numerical value. Signed-off-by: Robert C. Helling <helling@atdotde.de>
