BEWARE. The switch -lightmapsize is to be used WITHOUT shaders in engines
capable of external lightmaps, like DarkPlaces. It forces making the lightmaps
external... which is different from the "shader hack".

So if you change the meaning of this switch, please make sure that such engines
still can use the maps. DarkPlaces does NOT have sufficient Q3 shader
capabilities to support q3map_lightmapSize.

Probably, this should be two separate options.
