Lohikar bc441ab9d6 Miscellaneous Tweaks (#1720)
changes:

Refactored footstep sounds to use less operations & only calculate for human-types.
Improved the logging detail of the lighting profiler.
Fixed some shuttle corners that weren't correctly working with parallax space.
Converted get_turf() into a compiler macro.
Solars are now dynamically lit.
Silenced warning from lighting overlays pooling themselves when updated on a space tile.
Fixed a bug where securing a girder was instant when it was supposed to have a delay.
