Add telescience blocks on the mining Z-level

[BlackPhoenix]

Would it be possible to make crates have a teleport lock? If they are grabbed by a teleporter, they grind their contents? This risk would, obviously, have to come with nifty loot that'd be worth going out to grab crates by hand for. This way, you can still grab crates by teleporter, but there's a risk that you might trash some of your loot that way, and said possibly trashed loot is probably good stuff.
