Firelock opacity consistency (#62328)
Firelock opacity consistency (#62328)

Directional firelocks tried to block vision, unlike normal firelocks.
However, being able to stand on the same turf as an opaque object can
allow some really weird behavior - you can see through a closed directional
firelock if and only if you're on the same tile.

This changes it so that directional firelocks do not block vision.

Fixes #62106.
