Changed, Numeric textboxes: trailing zeros are no longer displayed to reduce visual noise. Fixed, paired numeric controls: in some cases culture-specific decimal separator was not used. Fixed, map loading: inability to initialize D3D device is now handled a bit more gracefully. Fixed, main toolbar context menu: we should suppress context menu closing only when user clicks on a menu item while holding Shift key. Fixed, Game configurations: several Skulltag things were not included in many Zandronum game configurations.
