0.8.2b hotfix

A quick fix:

• Fixed up some brightmaps
• Add GL lights to brightmapped pickups
• Try (and fail to) fix some effects in GZDoom getting stuck inside walls (I guess that’s just GZDoom for ya, can’t have parity even if I try)

If you were to ask me “how often do you update your projects?”, the answer would be simply “yes”.
