Expands medipens & mining

- 2 new medipens added, leporazine (regulates body temp) and stimpack (hyperzine with toxin)
- 10u of tricord added to the combat hypo, so it's not as useless for nuke ops
- Added an IV line to the miner's helmet (injects into neck) that allows them to use medipens and syringes by violently stabbing them into their necks like the junkies they are [removed the thickmaterial flag in other words]

For mining vendor:
- Chili (which was used to counter basilisk cold stare) replaced with leporazine medipen
- Stimulant pills (which were used to sanic the fuck away from hostile mobs if there was 2 goliaths on your ass) replaced with stimpack medipen

So trying to make it more balanced (since basilisks are fucking piss easy, and nobody used pills for anything but high speed griefing anyway rather than escaping from combat) is a bad thing now? Those pills that were in the vendor were better than what chemistry can make by default, which is hyperzine, which is what's in here now. You want super great chemistry pills? Go to chemistry. You want a way to get out of combat if you're in over your head? Use a stimpack.
