Power armor hauling frame
Hauling frame added to spawn lists
Spelling correction (supplimental to supplemental) in overmapp.cc
create_starting_npcs will not generate starting npcs if the no_npc.txt file exists.
Removed old data/nonpc.txt and no_npc.txt files. Added npc.txt you can set in the npc.txt file which npcs you want to spawn. The starting one or random spawn ones. All defaults are set to not spawn them.
small comment problem fixed
Added fix for npc spawning on top of other npc. It now searches in a spiral pattern for a free spot (a game->is_empty spot).
Added missing a few npctalk switch cases.
Add far-sighted as a trait, take penalties with no reading glasses

Added the Far-Sighted trait. If you're far-sighted and have no reading glasses on, you're unable to read and take a melee accuracy penalty.
Make Far-Sighted also apply a penalty to electronics/tailoring crafting

Added electronics/tailoring crafting penalties to far-sighted, after GlyphGryph suggested it.
Only crafting is penalized (not disassembly), because making things is more fiddly than taking them apart.
Only electronics/tailoring are affected (tailoring less so) because they seem the most reliant on fine detail vision.
