Global customization of light source radii

Many RPG systems have their own rules for how much bright and dim light various light sources give, which differ from the default values of DA's AI generation. This means if we want accuracy to our systems we either have to turn off generation of light sources entirely or manually adjust each light source, either in DA or our VTT (if exporting to one). The ability to globally (and numerically) set the illumination radius for each light source asset, which the AI generation would then use, would be a huge time saver and allow us to gain greater value from the light source generation.
