Add telescience blocks on the mining Z-level

[BaneOfGiygas]

Lots of places in the derelict-z are teleblocked. They wouldn't have access to it.

I've done some testing on this front, and have figured out places that are and aren't teleblocked in the debris field:

- Medical ship (note that it has the necroscanner and the grenade kit, two of the more noteworthy pieces of loot in the debris field)
- The X-Drone lair (contains an easter egg and the X-Drone itself)
- Fermid hell (also contains an easter egg, and obviously fermids)
- That one asteroid with the zip gun and seven abandoned crates

Places that are teleblocked:

- The Z-Drone (pretty much no discernible loot found to date)
- Hemera (there's the obsidian crown, I think a module for the GuardBuddies, and some telecrystals)
- Martian Station (has a few abandoned crates and that one merchant guy, all of which can be acquired without physically encountering so much as a single hostile Martian. All the rest is just random knickknacks.)

The places in the debris field with the most noteworthy loot are also the places that are easiest to get into, and the places in the debris field that ARE teleblocked, while larger and more dangerous, don't have loot anywhere near as noteworthy as the stuff you can nick from other places. Hell, the Z-Drone doesn't even have any loot, period. Maybe that's what should change, really.
