Allow surgery on crashed ships (and new tile variants allowing surgur…

…y & construction) (#5579)

# About the pull request

following quote outdated...
```
I INSTANCE edited the turfs/floor tiles for the nightmare inserts for:
Solar (Big Red)
Desert Dam

I edited the files to:
Supports_surgery 1
(enabled surgury. Default value is 0)
```

made proper new tiles and replaced in many map files & nightmare inserts


# Explain why it's good for the game
Allows people to fucking DO SURGURY!
Literally ruined someone's entire round because I couldn't fix his IB
and by the time I did, 4 T3 were there and he got got.



# Testing Photographs and Procedure

Start at 1:10. I fixed that other tile variant not allowing surgury at
the end of the video.

DW, reverted CC map file changes for my testing tiles.
