- refined light mode selection.

Browse source 
This is to ensure that if the map specifies light mode Doom (i.e. hardware approximation of software lighting) it is not overridden by the user-selected software emulating light mode.
gl_lightmode should only apply if neither the map nor gl_maplightmode set an explicit light mode.
