trench/mining rework

Honestly, in terms of progression, I always thought it'd be cool to actually mine downwards. I've seen videos of other SS13 servers' mining where there's a lot more 'depth' (pun intended) to the mining levels. Something like being able to construct a shaft further down into the trenches would be interesting.

You could do something like the adventure map and divide the trench map into smaller sections that represent those depths. Then you just punch a hole down and teleport to that other section.
Would work great for mappers to build floor modules knowing they had a certain area to work with. Just a small dungeon floor with an established entrance and exit. Trench map pulls a few modules, links their entrances and exits, and you've got a dungeon crawler miner metagame
