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

You could just set medipens to have the ignore_flags var set to 1, meaning they'll ignore the THICKMATERIAL flag without making mining suits vulnerable to syringe guns.
