Cataclysm-dda: designating a firewood source should not require light

[joe9000]

currently, "constructing" a firewood source can't be done in the dark, which seems weird. suggest removing the requirement for lighting.

I would say this should be moved to zone management instead.

i agree as a long term solution that adding a Loot: Usable Wood zone type and potentially a Loot: Usable Batteries and a Loot: Usable Liquid Fuels would be a great idea, replacing firewood source under construction.

not sure how much dev time would be needed for that solution, so i think removing the darkness requirement would be an adequate near term fix.
