Remove or reduce spatial tears

[kyle2143]

I once made a patch to change spatial tears before I was an admin that I thought was a good compromise for changing them from being very tedious and boring. It didn't get an overly positive reception iirc so I never merged it as an admin but here's the gist:
Spatial tears can be crossed, but when you enter a spatial tear tile you are spit out on a random tile adjacent to the tear on the opposite side, taking some damage, possibly losing a limb or organ. Making them still quite dangerous to cross, but not if you take preparations. I also made an event that is multiple spatial tears for more chaos.

Here's the patch. https://forum.ss13.co/showthread.php?tid=10517
