Darkness Fixes & Shell Tweaks (#2066)

changes:

ChangeTurf no longer breaks lighting when switching from statically lit turfs to dynamically lit turfs.
Human-types' is_noisy value is now updated on spawn; boots should now make footstep SFX without having to take them off and put them back on.
Fixed a logic error in is_noisy calculations which could have lead to false-negatives.
Shells can now wear socks & undershirts.
Fixed a bug where changing the dynamic lighting status on an area would attempt to build lighting overlays for the entire map.
Fixes #2027.
Fixes #1982.
