            Fix bug coincidentally resulting in Graphics Detail value cycling 
            when left arrow is pressed.
            
            OOGraphicsDetail is an enum type and as such it will never go 
            negative. The following code adjusts "direction" to avoid illegal
            detailLevel values.
            
            Perhaps a more elegant solution could be set in place, restructuring 
            in Universe.m the logic behing setDetailLevelDirectly and 
            setDetailLevel, not forgetting to consider Graphic Detail assigned 
            from various sources (i.e. menu, user prefs file, javascript, etc.). 
            This is postponed in order not to risk the recently announced 
            plans for v1.82 release.
            
            Generally we should decide whether the menu values should cycle or 
            not and apply it for all menu entries.
