- RepairTools work for structures that are outside the submarine

- Ruins are visible in sonar
- Fixed ruin generation algorithm occasionally creating too narrow rooms and placing corridors so that they're blocked by corners of a room
- Fix for wall textures being misaligned for map cells with no physics body
