Subject: In my crusade against facelights, I am striking the killing blow. Add
 a DisableFacelights option to OpenSim.ini to finally kill those immersion-
 breaking, silly vanity lights that destroy nighttime RP. Girls, you look just
 fine without them. Guys, you too. Thank you. Melanie has left the building.
