Per bugs/942, the server has problems dealing with glow_radius larger
than 4. I reviewed the maps using absurdly high (>= 12) glow_radius and
removed them where they had no business having them. These changes fell
into the category of:
- There is no darkness or outdoor flag, so remove the light4
- Object with custom glow_radius, but no darkness or outdoor flag, so
remove glow_radius line
- Unlinked maps
