Bluespace Mining (#8492)

Implements bluespace mining, or: How to keep your lousy ore box at home.
While it may sound complex, it's actually fairly simple once you get it down. This is an attempt to make mining a little more 24XX, as well as introducing a way for mining drills to not be awful.

    Bluespace mining is now possible, to do so, attach a warp extraction pack to a mining satchel, then a warp extraction beacon signaller to an ore box. Link them by clicking on the ore box with the satchel.
    You can attach a linked mining satchel to a mining drill to teleport mined ores to the connected ore box.
    Mining satchel beacons can be removed with a screwdriver, mining drill satchels by wrench, and ore box beacons by hand.
