One runtime fixed, other one didn't turn up.
I put in some stuff for it to be easier to find if it does.
Fixed an annoying bug with giving another player a flashlight,
opened up at least 100 individual bugs where people kept setting
loc and expecting light updates to catch it.
I think I fixed everything it is possible to stuff a light source into.
Fixed issues with cyborgs deactivating flashlights, cleaned up some module code in the process.
Added the ability to use multiple light icons to represent over four states.
Reduced six-state lighting to five-state, removed debug verbs.
Not a big drop in quality, but reduces the states used by half.
