Mining changes + mini reworks

[JohnnyJohn]

Just a batch of changes for mining in general!

• Digbots fight nanites and have a mining laser by default, when printed from the fabricator
  
• Industrial armor can protect against plutonium, and heavily negates bleed
  
• Mining PDAs can interface with the magnet and control it's activation/target/override and see it's status
  
• Geoscanners can "diffuse" volatile compounds before they detonate
  
• Nanites glow so they're more visible against space
  
• Mining fabricators can print weak EMP and anti-zombie grenades to deal with the problems that the magnet can pull up
  
• Mining phasers on pods get buffed
  
• Replacement for the quantum telescope (explained below)
  

While scientists still have the quantum telescope, miners will now get the radiological astroscanner, which can convert atomic radiation into radio frequencies to help locate them. Upon using this, miners will get a menu presenting buttons and dials, and a sort of RF oscilloscope to show the signal. They will have to fiddle with different settings to hone in the signal, and identify what kind of asteroid it is. Once found, it can be repeated.
That being said, most frequencies are unknown, and they are shuffled roundstart. Only a few ore types (mauxite, pharosium, etc) are known roundstart, the rest you'll just have to figure out yourself. Once you do, you can record it, and know what settings to hone and where to look to get the asteroid you need! (Does not work on aquatic maps.)
